论文摘要
作为强核力量的重要组成部分，张量化的力产生了各种有趣的效果，从几岁的系统到中子恒星。它负责超出平均场近似之外的核子核子相关性，因此被证明在当前工作中在标准的Skyrme能量密度函数中没有任何作用。因此，目前广泛雇用的Skyrme的原始张量相互作用是无效的。 As an alternative strategy, we introduced a central interaction, i.e., the $\bm{σ}_{1}\cdot \bm{σ}_{2}$ term, to improve the description of experimental single-particle structure, and to address its effect, we established two Skyrme interactions IMP1 and IMP2 complemented by the calibrated charge-violating interactions.中央$ \ bm {σ} _ {1} \ cdot \ bm {σ} _ {2} $相互作用可实质上改善了SN同位素中Shell Evolution的描述，$ n = 82 $ isotones。
The tensor force, as an important component of strong nuclear force, generates a variety of intriguing effects ranging from few-body systems to neutron stars. It is responsible for the nucleon-nucleon correlation beyond mean-field approximation, and is accordingly proved to play no role in the standard Skyrme energy density functionals in the present work. Therefore, the Skyrme's original tensor interaction that is extensively-employed presently is invalid. As an alternative strategy, we introduced a central interaction, i.e., the $\bm{σ}_{1}\cdot \bm{σ}_{2}$ term, to improve the description of experimental single-particle structure, and to address its effect, we established two Skyrme interactions IMP1 and IMP2 complemented by the calibrated charge-violating interactions. The central $\bm{σ}_{1}\cdot \bm{σ}_{2}$ interaction turns out to substantially improve the description of shell evolution in Sn isotopes and $N=82$ isotones.
