| 1 | Carbon dioxide reforming of methane over mesoporous nickel aluminate/γ-alumina composites显示文摘A series of x NiAl_2O_4/γ-Al_2O_3 composites with various Ni contents have been prepared via one-step partial hydrolysis of metal nitrate salts in the absence of surfactants and used for carbon dioxide reforming of methane. The characterization results demonstrated that the Ni Al_2O_4/γ-Al_2O_3 materials possessed mesoporous structures of uniform pore sizes; and the Ni^(2+) ions were completely reacted with alumina to Ni Al_2O_4 spinel in the matrices using N2 sorption, XRD, TEM, and XPS. The Ni Al_2O_4/γ-Al_2O_3 materials exhibited excellent catalytic properties and superior long-term stability for carbon dioxide reforming of methane. The effects of Ni content on the intrinsic activities and the amounts of coke disposition of the x NiAl_2O_4/γ-Al_2O_3 catalysts were discussed in detail for the carbon dioxide reforming of methane. The results revealed that the Ni particle sizes did not affect the intrinsic activity of metallic Ni, but smaller Ni particles could reduce the rate of coke deposition. | Li Zhang Xueguang Wang Xingfu Shang Mingwu Tan Weizhong Ding Xionggang Lu | 2017 | Journal of Energy Chemistry2017，26，1： | 2 |

| 3 | 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 |

| 5 | 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 |
| 6 | 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 |
| 7 | 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 |
| 8 | 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 |
