| 1 | Progress of Jinping Underground laboratory for Nuclear Astrophysics(JUNA)显示文摘Jinping Underground laboratory for Nuclear Astrophysics(JUNA) will take the advantage of the ultra-low background of CJPL lab and high current accelerator based on an ECR source and a highly sensitive detector to directly study for the first time a number of crucial reactions occurring at their relevant stellar energies during the evolution of hydrostatic stars. In its first phase, JUNA aims at the direct measurements of^(25)Mg(p,γ)^(26)Al,^(19)F(p,α)^(16)O,^(13)C(α,n)^(16)O and ^(12)C(α,γ)^(16)O reactions. The experimental setup,which includes an accelerator system with high stability and high intensity, a detector system, and a shielding material with low background, will be established during the above research. The current progress of JUNA will be given. | WeiPing Liu ZhiHong Li JiangJun He XiaoDong Tang Gang Lian Zhu An JianJun Chang Han Chen QingHao Chen XiongJun Chen ZhiJun Chen BaoQun Cui XianChao Du ChangBo Fu Lin Gan Bing Guo GuoZhu He Alexander Heger SuQing Hou HanXiong Huang Ning Huang BaoLu Jia LiYang Jiang Shigeru Kubono JianMin Li KuoAng Li Tao Li YunJu Li Maria Lugaro XiaoBing Luo HongYi Ma ShaoBo Ma DongMing Mei YongZhong Qian JiuChang Qin Jie Ren YangPing Shen Jun Su LiangTing Sun WanPeng Tan Isao Tanihata Shuo Wang Peng Wang YouBao Wang Qi Wu ShiWei Xu ShengQuan Yan LiTao Yang Yao Yang XiangQing Yu Qian Yue Sheng Zeng HuanYu Zhang Hui Zhang LiYong Zhang NingTao Zhang QiWei Zhang Tao Zhang XiaoPeng Zhang XueZhen Zhang ZiMing Zhang Wei Zhao Zuo Zhao Chao Zhou | 2016 | Science China(Physics,Mechanics & Astronomy)2016，59，4： | 3 |
| 2 | A proposed direct measurement of cross section at Gamow window for key reaction 19F(p,α) 16O in Asymptotic Giant Branch stars with a planned accelerator in CJPL显示文摘In 2014, the National Natural Science Foundation of China(NSFC) approved the Jinping Underground Nuclear Astrophysics laboratory(JUNA) project, which aims at direct cross-section measurements of four key stellar nuclear reactions right down to the Gamow windows. In order to solve the observed fluorine overabundances in Asymptotic Giant Branch(AGB) stars, measuring the key ^(19)F( p,α)^(16)O reaction at effective burning energies(i.e., at Gamow window) is established as one of the scientific research sub-projects. The present paper describes this sub-project in details, including motivation, status, experimental setup, yield and background estimation, aboveground test, as well as other relevant reactions. | JianJun He ShiWei Xu ShaoBo Ma Jun Hu LiYong Zhang ChangBo Fu NingTao Zhang Gang Lian Jun Su YunJu Li ShengQuan Yan YangPing Shen SuQing Hou BaoLu Jia Tao Zhang XiaoPeng Zhang Bing Guo Shigeru Kubono WeiPing Liu | 2016 | Science China(Physics,Mechanics & Astronomy)2016，59，5： | 3 |
| 3 | Nuclear uncertainties in the s-process simulation显示文摘The heavy elements in the Universe are formed during the s- and r-processes mainly in AGB stars and supernovae, respectively. Simulation of s- and r-nucleosynthesis critically depends on the neutron capture and weak decay rates for all the nuclei on the reaction chain. The present work analyzes systematically the neutron capture rates (cross sections) for the s-process nuclei, including ~3000 rates on ~200 nuclei. The network calculations for the constant temperature s-process have been performed using the different data sets selected as the nuclear inputs to investigate the uncertainties in the predicted s-abundances. We show that the available cross sections of neutron capture on many s-process nuclei still carry large uncertainties, which lead to low accuracy in the determination of s-process isotope abundances. We analyze the neutron capture cross section data for the same unique isobar nucleus accorded by year from previous work. Such an analysis indicates that the s-process has been studied for more than fifty years and there exist two research stages around 1976 and 2002, respectively. The needs and opportunities for future experiments and theoretical tools are highlighted to remove the existing shortcomings in the neutron capture rates. | ZHANG YouJin CHEN YongShou GUO JianYou HOU SuQing LI ZhiHong SHI JianRong | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，5： | 2 |

| 8 | 通过^(1)H(^(15)O,p)^(15)O弹性散射来研究^(16)F的能级性质显示文摘The understanding of open quantum systems in unbound nuclei is a challenge to the nuclear structure research[1].The continuum coupling effect may lead to a reordering of the shells in such systems[2].A way to study this effect is to compare the level schemes of two mirror nuclei involving an unbound and a bound nucleus such as 16F and 16N[3].Here we report an experiment of studying the level properties of 16F using the resonant elastic scattering with an 15O radioactive beam delivered by the Radioactive Ion Beam Line at Lanzhou(RIBLL)[4]. | Ru Longhui Hu Jun Liu Enqiang Bai Zhen Duan Fangfang Fang Xiao Hou Suqing Hu Qiang Ji Liancheng Jin Shuya Li Kuoang Li Yiyang Li Ruojie Ma Peng Ma Junbing Sun Xinxin Shi Guozhu Tang Xiaodong Wang Xinyu Wang Jiansong Wang Yufeng Wu Jiatong Xu Xiaodong Xu Shiwei Xin Wenyu Yang Kaiping Yang Yanyun NMichel | 2018 | IMP & HIRFL Annual Report2018，，1： | 0 |

| 14 | 2-13 New Solution to Cosmological Lithium Problem显示文摘In the Big Bang theory,primordial nucleosynthesis was finished during first half hour of the universe’s existence.This process yielded the main light elements including hydrogen,deuterium,helium and lithium.The theoretical predictions match very well the observed deuterium and helium abundance,but the 7Li abundance is overpredicted by a factor a three[1].This inconsistency is called“cosmological lithium problem”.In the past decade,many attempts to solve this problem using conventional astrophysics and nuclear physics failed.Recently,we proposed a new solution to lithium problem by introducing non-extensive statistics into Big Bang nucleosynthesis[2]. | Hou Suqing He Jianjun | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
| 15 | 2-16 Experimental Study of 13N(α,p)16O at the Stellar Energies显示文摘The presolar SiC grains[1]carry the original stellar nucleosynthesis signature.Their isotopic anomalies compared to the sun are the strong constrains in the supernovae(SN)model calculations.The 15N-excess in some SiC-AB grains(12C/13C<10 and 14N/15N<272)is one of the challenges of core-collapse supernovae(CCSNe)models[2].Recently,Pignatari pointed out that the entrainment of H-rich material into the He shell before the SN explosion allows the coproduction of 13C,15N and 26Al,which provides a new production scenario for SiC-AB grains[2].In the He shell nucleosynthesis,the 13C is produced through 12C(p,γ)13N(β+γ)13C reaction.The 14N is synthesized through 13N(n,γ)and 13C(p,γ)reactions. | Lin Weiping Ma Shaobo Hu Jun Bai Zhen Chen Han Chen Zhijun Duan Fangfang Gao Bingshui Gao Zhihao Hou Suqing Ji Liancheng Jia Baolu Jiao Lei Jin ShuYa Liu Xingquan Li Kuoang Lu Tan Ma Junbing Ma Peng Tang Xiaodong Wang Xinyu Xu Shiwei Yang Yanyun Yu Gongming Yu Xiangqing Zhai Yaojie Zhang Ningtao Zhang Xing | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
| 16 | 2-8 Measurement of 11B(p,r)12 C Astrophysical S Factors at Low Energies显示文摘Theoretical models of stellar evolution predict negligible quantities of 6Li, 9Be, and 11B in the hydrogen burning phases of a star’s evolution[1]. The primordial Big-Bang nucleosynthesis (BBN) model might be more generous in its production of these elements[2]. The radiative-capture cross section for proton capture on 11B leading to 12C is small at astrophysically interesting energies because of the large Coulomb barrier. | He Jianjun Xu Shiwei Jia Baolu Chen Size Ma Shaobo Hou Suqing Hu Jun Zhang Liyong Yu Xiangqing | 2015 | IMP & HIRFL Annual Report2015，，1： | 0 |
