基于Weizscker-Skyrme核质量公式研究原子核基态性质

Study on Ground State Properties of Nuclei with Weizscker-Skyrme Nuclear Mass Formula

基于一个半经验的原子核宏观-微观质量公式——Weizscker-Skyrme质量公式,研究了原子核的形变、滴线、壳能隙和超重核α衰变能等相关性质,发现该模型能较好地再现实验结果。与此同时,探索了原子核对称能系数对原子核质量公式的影响和超重稳定岛的可能位置。

Based on a semi-empirical macroscopic-microscopic nuclear mass formula——Weizscker-Skyrme mass formula,some ground properties of nuclei,such as the deformations,the drip lines,the shell gaps of nuclei and the α-decay energies of some super-heavy nuclei have been studied.The experimental data can be reasonably well reproduced with this formula.In addition,the nuclear symmetry energy coefficient and the central position of super-heavy stability island were investigated.
