| 3 | 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.

| 4 | Parametrization of woods-saxon potential for heavy-ion systems显示文摘Several elastic scattering angular distributions of ^(12)C from target nuclei of A ≥39 are analyzed to extract the Woods-Saxon potential parameters with the fixed imaginary potential and Coulomb radius parameters.Using the best fitted diffuseness parameters,the correlations of the real part parameters with A_1^(1/3)+ A_2^(1/3) and incident energy are revealed, and the systematic Woods-Saxon potential parameters are presented for nucleus-nucleus interaction.The proposed potential parameters can reproduce not only the elastic scattering angular distributions induced by ^(12)C,but also many elastic scattering angular distributions induced by the projectiles other than ^(12)C,thus providing important inputs for the study of nuclear reactions of heavy-ion systems. | Lin Gan ZhiHong Li HuiBin Sun DanYang Pang Bing Guo YunJu Li Jun Su ShengQuan Yan ErTao Li YouBao Wang Gang Lian ZhiYu Han XinYue Li DongHui Li TianLi Ma ChangJin Pei YangPing Shen Yi Su Sheng Zeng Yong Zhou WeiPing Liu | 2017 | Science China(Physics,Mechanics & Astronomy)2017，60，8： | 2 |
| 5 | Empirical formula for β^--decay half-lives of r-process nuclei显示文摘Experimental data ofβ--decay half-lives of nuclei with atomic number between 20 and 190 are investigated.A systematic formula has been proposed to calculateβ^--decay half-lives of neutron-rich nuclei,with a particular consideration on shell and pair effects,the decay energy Q as well as the nucleon numbers(Z,N).Although the formula has relatively few parameters,it reproduces the experimentalβ^--decay half-lives of neutron-rich nuclei very well.The predicted half-lives for the r-process relevant nuclei obtained with the current formula serve as reliable input in the r-process model calculations. | Yong Zhou ZhiHong Li YouBao Wang YongShou Chen Bing Guo Jun Su YunJu Li ShengQuan Yan XinYue Li ZhiYu Han YangPing Shen Lin Gan Sheng Zeng Gang Lian WeiPing Liu | 2017 | Science China(Physics,Mechanics & Astronomy)2017，60，8： | 1 |
