| 1 | Rb-Sr and Sm-Nd Isochron Ages of the Dongmozhazhua and Mohailaheng Pb-Zn Ore Deposits in the Yushu area, southern Qinghai and Their Geological Implications显示文摘Located on the northeast margin of the Qiangtang terrane between the Jinshajiang suture zone and Bangonghu-Nujiang suture zone, the Dongmozhazhua and Mohailaheng Pb-Zn deposits in the Yushu area of Qinghai Province are representative Pb-Zn deposits of the Pb-Zn-Cu polymetallic mineralization belt in the northern part of the Nujiang-Lancangjiang-Jinshajiang area, which are in the front belt of the Yushu thrust nappe system. The formed environments of these two deposits are different from those of sediment-hosted base metal deposits elsewhere in the world. The authors hold that they were formed during the Indian-Asian continental collision and developed within the foldthrust belt combined with thrust and strike-slip-related Cenozoic basins in the interior of the collisional zone. Studying on the metallogenic epochs of these two deposits is helpful to the understanding of ore-forming regularity of the regional Pb-Zn-Cu mineralization belt and also to the search for new deposits in this region. The age of the Dongmozhazhua deposit has been determined by the Rb-Sr isochron method for sphalerite residues, whereas the age of the Mohailaheng deposit has been determined by the Rb-Sr isochron method for sphalerite residues and the Sm-Nd isochron method for fluorite. The age of the Dongmozhazhua deposit is 35.0±0.0 Ma((87Sr/86Sr)0=0.708807) for sphalerite residues. The age of the Mohailaheng deposit is 32.2±0.4 Ma((87Sr/86Sr)0=0.708514) for sphalerite residues and 31.8±0.3 Ma((143Nd/144Nd)0=0.512362) for fluorite with an average of 32.0 Ma. Together with the regional geological setting during mineralization, a possible tectonic model for metallogeny of the Dongmozhazhua and Mohailaheng Pb-Zn deposits has been established. These two ages are close to the ages of the Pb-Zn deposits in the Lanping and Tuotuohe basins, indicating that it is possible that the narrow 1000-kilometer-long belt controlled by a thrust nappe system on the eastern and northern margins of the Tibetan plateau could be a giant Pb-Zn mineralized belt. | TIAN Shihong GONG Yingli YANG Zhusen HOU Zengqian LIU Yingchao SONG Yucai XUE Wanwen LU Haifeng WANG Fuchun ZHANG Yubao ZHU Tian YU Changjie | 2014 | Acta Geologica Sinica(English Edition)2014，88，2： | 8 |

| 3 | Triphenylphosphonium-modified mitochondria-targeted paclitaxel nanocrystals for overcoming multidrug resistance显示文摘Mitochondria are currently known as novel targets for treating cancer,especially for tumors displaying multidrug resistance(MDR). This present study aimed to develop a mitochondriatargeted delivery system by using triphenylphosphonium cation(TPP+)-conjugated Brij 98 as the functional stabilizer to modify paclitaxel(PTX) nanocrystals(NCs) against drugresistant cancer cells. Evaluations were performed on 2 D monolayer and 3 D multicellular spheroids(MCs) of MCF-7 cells and MCF-7/ADR cells. In comparison with free PTX and the non-targeted PTX NCs,the targeted PTX NCs showed the strongest cytotoxicity against both2 D MCF-7 and MCF-7/ADR cells,which was correlated with decreased mitochondrial membrane potential. The targeted PTX NCs exhibited deeper penetration on MCF-7 MCs and more significant growth inhibition on both MCF-7 and MCF-7/ADR MCs. The proposed strategy indicated that the TPP+-modified NCs represent a potentially viable approach for targeted chemotherapeutic molecules to mitochondria. This strategy might provide promising therapeutic outcomes to overcome MDR. | Xue Han Ruijuan Su Xiuqing Huang Yingli Wang Xiao Kuang Shuang Zhou Hongzhuo Liu | 2019 | Asian Journal of Pharmaceutical Sciences2019，14，5： | 1 |

| 5 | 4-10 A 128-channel Picoammeter System and Its Application on Charged Particle Beam Current Distribution Measurements显示文摘The absolute current distribution is usually the most desirable parameter in experiments involving a charged particle beam. The Faraday cup array technique, a direct measurement of the absolute current distribution, has been developed both in one dimension[1] and two dimensions[2], providing a great advantage in terms of convenience. In this technique, a many-channel picoammeter (up to 128 channels) is necessary. | Yu Deyang Liu Junliang Xue Yingli Zhang Mingwu Cai Xiaohong Hu Jianjun Dong Jinmei | 2015 | IMP & HIRFL Annual Report2015，，1： | 0 |
| 6 | 4-11 Determination of Target Thickness and Luminosity from Beam Energy Losses at HIRFL-CSRe Internal Target显示文摘The experiments with an internal target at a storage ring have many advantages. However, it is difficult to determine the absolute cross section of a reaction where luminosity cannot be simply established through macroscopic measurements. Here we present an experimental determination of the effective target thickness from the beam energy losses at the internal target in HIRFL-CSRe. The measurements here are expected to provide the accurate target thickness and luminosity for the absolute cross-section study on future internal target experiments, and also provide some reference values for the study of beam loss mechanism of the heavy ion at HIRFL-CSRe. | Shao Caojie Yu DeYang Lu Rongchun Xue Yingli Wang Wei Yang Bian Zhang Mingwu Liu Junliang Song Zhangyong Cai Xiaohong | 2015 | IMP & HIRFL Annual Report2015，，1： | 0 |
| 7 | 4-12 Electron Beam Guiding by Grooved SiO2 Parallel Plates without Energy Loss显示文摘Since the unexpected guiding effect of low energy ions by PET nanocapillaries was reported in the last decade[1], the self-organized charge-up on insulating surface is employed to realize a self-adaptive manipulation of charged particle beams[2–4]. Considerable work (see Ref. [5] and references therein) has been done to investigate slow highly charged ions (SHCIs) interacting with inner surface of various insulating capillaries[5]. | Xue Yingli Yu Deyang Liu Junliang Zhang Mingwu Yang Bian Zhang Yuezhao Cai Xiaohong | 2015 | IMP & HIRFL Annual Report2015，，1： | 0 |

| 10 | 4-18 Single and Double Electron Capture by Fast Xe54+ from Kr and Xe显示文摘When an energetic highly charged ion (HCI) collides with an atom, the target electrons may be captured by theprojectile ion, either radiatively or non-radiatively. During a radiative electron capture (REC), a target electronis transferred to the projectile accompanying with a photon emission, which carries away the excess energy andmomentum. During a non-radiative electron capture (NRC), the energy and momentum conservations are ensuredby the target nucleus[1]. If the captured electrons are populated in excited states, photons maybe emitted duringthe following stabilization processes, and therefore the X-ray spectrum can provide information about the initialpopulation. However, if a solid target is employed, the single-collision condition cannot be ensured when consideringthe capture processes, as well as strong background will be produced[2]. With the development of heavy ioncooling storage rings, the experimental luminance is enhanced by the strong ion beams when a gaseous target isprerequisite[3]. | Yu Deyang Shao Caojie Lu Rongchun Wang Wei Liu Junliang Xue Yingli Song Zhangyong Zhang Mingwu Yang Bian Ruan Fangfang Cai Xiaohong | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
| 11 | 4-19 Double K-shell Ionization of Kr Induced by Swift Xe54+ Ions显示文摘Double K-shell ionization of atoms by collisions with charged ions is one of typical two-electron processes andattracts considerable attention both in term of basic theory and experiment. Radiative de-excitation of the doubleK-shell vacancy states of atoms leads to the emission of so called K X-ray hyper-satellites (Kh,Kh . . . )[1], whichgives us the insight into the decay modes of multiply ionized ions as well as the ionization processes during ion-atomcollisions. Contrary to the long-winded and difficult experiments with heavy target due to the low detection efficiencyof K X-ray hyper-satellites with crystal spectrometers[2??4], the bulk of knowledge concerning double K-shellionization in ion-atom collisions has been obtained for light target. | Shao Caojie Yu Deyang Wang Wei Xue Yingli Zhang Mingwu Yang Bian Song Zhangyong Lu Rongchun Liu Junliang Cai Xiaohong | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
| 12 | 4-20 Electrons Guiding through a Plate Capillary显示文摘The guiding effect of 3 keV Ne7+ ions passing through an insulating PET nanocapillaries was found in 2002by N. Stolterfoht et al[1]. Since then considerable work[2] has been done to investigate slow highly charged ions(HCIs) interacting with inner surfaces of various insulating capillaries. It has been shown that the guiding effect isprevalent in the transmission of slow HCIs.Similar guiding phenomena were also observed for electrons transmitted through capillaries (see, e.g., Ref. [3-5]).However, the experiments showed that transmission efficiency of electrons was significantly lower than that of HCIs.Moreover, it revealed that portion of the transmitted electrons suffered significant energy-loss. | Xue Yingli Yu Deyang Liu Junliang Zhang Mingwu Yang Bian Zhang Yuezhao Cai Xiaohong | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
| 13 | 以自组织方式实现快速离子导向显示文摘Although great attention has been paid to study the guiding effects of charged ions through insulating nanocapillaries or a single microcapillary[1]since the pioneering work of Stolterfoht et al.in 2002[2],the same high standard of reproducibility and accuracy among different laboratory cannot be expected because the bulk and surface conductivities of an insulating material are often not well characterized and depend strongly on the working conditions.In other words,the guiding processes are rather random than controllable.In addition,with the energy increasing,the incomplete guiding effect[3;4]limits the application of guiding a swift ion beam in a self-organizing way. | Xue Yingli Yu Deyang Liu Junliang Zhang Mingwu Song Xiaoxun Hui Xinfei Yang Bian Shao Caojie Song Zhangyong Wang Wei Cai Xiaohong | 2018 | IMP & HIRFL Annual Report2018，，1： | 0 |
| 14 | Angular Distribution of Lyman-1 Transition Following Nonradiative Electron Capture into Xe^53+Ions显示文摘Radiative electron capture(REC)and nonradiative capture(NRC)are two competing mechanisms in relativistic collisions of highly charged ions with atoms[1].REC means electron transfer from target to projectile with the emission of one photon for satisfying energy and momentum conservation laws. | Yang Bian Yu Deyang Cai Xiaohong Shao Caojie Xue Yingli Wang Wei Zhang Mingwu Liu Junliang Song Zhangyong Wu Yehong Lu Rongchun Ruan Fangfang | 2019 | IMP & HIRFL Annual Report2019，，1： | 0 |

| 16 | 基于HOPG的广角高效X射线晶体谱仪显示文摘In collisions between fast heavy ions and atoms,the strong Coulomb field of one of collision partners can cause inner-shell multiple-ionization of the second one[1].The high-resolution measurements of emitted X-rays in the collision are one of the most effective methods to study the multivacancy configurations in atoms or ions as well as the dynamics of the multiple ionization process.The energy shifts of X-rays from states with different vacancy configuration could be large[2].For example,the energy of the argon K hypersatellite and satellite line is between 2.9 and 3.8 keV,and the energy shift causing by per L hole is close to 20 eV[3].In order to simultaneous detection of the emitted X-rays over a wide energy range,thus avoiding the problem of changing the angle of crystal and position of the CCD in one collision system,a wide-angle and high-efficiency X-ray spectrometer based on flat HOPG(Highly Oriented Pyrolytic Graphite)crystal was developed.Due to X-ray from multi-ionized atoms. | Shao Caojie Yu Deyang Wang Wei Yang Bian Liu Junliang Xue Yingli Zhang Mingwu Song Zhangyong Cai Xiaohong | 2018 | IMP & HIRFL Annual Report2018，，1： | 0 |
| 17 | 平行板组件对4.2-18.2 keV Ar^(2+)离子的导向效应显示文摘Since the pioneering work of Stolterfoht etal[1],the guiding of low energy(keV)charged ions through insulating nanocapillaries or a single microcapillary has been received considerable attention in the last decade[2].The appearance of the incomplete guiding with increasing of the ions energy[3,4]indicates that the effective guiding potential(usually only tens volts)is far from compensating the transverse energy of the ions. | Xue Yingli Yu Deyang Liu Junliang Zhang Mingwu Yang Bian Wei Wang Cai Xiaohong | 2017 | IMP & HIRFL Annual Report2017，，1： | 0 |
| 18 | 离子与不同气体靶原子碰撞中的K壳双电离研究显示文摘In collisions between energetic heavy ions and atoms,the strong Coulomb field of one of collision partners can cause double K-shell ionization of the second one.In previous work we have studied the mechanism of double K-shell ionization in krypton atom by bare xenon under different perturbation strengths κ=Zp/vp,where Zp is the charge of the projectile and vp is its velocity in atomic units.The measured double-to-single K-shell ionization cross-section ratio is proportional to the perturbation strengthin the rough region of κ<1,but shows less rapidly increasing when κ>1[1].In order to further investigate such process in a wide rang of perturbation strength,an experiment focusing on K-shell ionization of ions was carried out at HIRFL-CSR in 2017.Ni19+ions with a energy of 95 MeV/u were stored in CSRe to interact with hydrogen,argon,krypton and xenon target,respectively.The X rays produced in collisions of the ions with the target were detected by two Silicon Drift Detectors(SDD)mounted at 35◦and 60◦observation angles with respect to the ion beam direction. | Shao Caojie Yu Deyang Wang Wei Yang Bian Liu Junliang Xue Yingli Zhang Mingwu Song Zhangyong Cai Xiaohong | 2017 | IMP & HIRFL Annual Report2017，，1： | 0 |
| 19 | 50-200 MeV/u全裸氙离子与氪、氙气体靶碰撞的电子俘获及辐射退激发显示文摘In collisions between energetic highly charged ions and atoms,the ions could remove the electrons of the target atoms,or be excited into high-level states.In the first case,the target electrons not only be captured into ground and excited states of the projectile ions,but also be ionized to free.Non-radiative capture(NRC)and radiative electron capture(REC)are two competing mechanisms in fast collisions[1].NRC means electron transfer from a bound state of the target to a bound states of the projectile without the emission of radiation;REC is produced with simultaneous the emission of photon for satisfying energy and momentum conservation laws.The physical essence is the competition between the“electron-nucleus”interaction and the“electron-vacuum”interaction.NRC is dominant in collisions of high-Z ions with heavy target atoms at moderate energies.REC entirely determine the electron capture channel for high collision velocities and light targets[1].Measuring the relative strength of the projectile x-ray emission associated with electron capture could determine state-selective population,angular distribution of single capture Ly 1 or double capture Kα1 and Kα2,would provide new detailed information on the dynamics of ion-atom collisions and atomic structure studies[1]. | Yang Bian Yu Deyang Cai Xiaohong Xue Yingli Shao Caojie Wang Wei Liu Junliang Zhang Mingwu Song Zhangyong Wu Yehong Lu Rongchun Ruan Fangfang | 2017 | IMP & HIRFL Annual Report2017，，1： | 0 |
| 20 | 3-13 Guiding of Electron Beams by Macro-insulating Units显示文摘In our previous work[1],using a pair of grooved SiO2 parallel plates,we had obtained stably guided electron beams without energy loss in the incident energy range of 8002 000 V.The very high-current(up to tens or hundreds of nA/mm2)electron beams were adopted.A 128-strip electrode array with a 128-channel picoammeter system[2],combined with an electrostatic deflector were employed to monitor the transmitted electron beams.To better understanding the guiding processes of electron beams passing through the insulting plates,several grooved parallel plates made by different insulating materials were adopted to study the dependence relative to the guiding beams on the conductivities of these materials.As shown in Fig. | Zhang Mingwu Xue Yingli Li Xin Liu Juliang Yang Bian Wang Wei Guo Yipan Xi Wei Zhu Xiaona Yang Liping Yu Deyang Shao Caojie Cai Xiaohong | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
