在轴向形变Skyrme Hartree-Fock(DSHF)+BCS模型框架下,研究了Skyrme相互作用的时间奇场对中子奇偶质量差的影响.为此,我们考虑时间偶场和时间奇场来计算半魔Ca,Ni和Sn同位素链的单中子和双中子分离能和配对能隙。在计算中,在Skyrme相互作用SLy 4、SLy 6和SkM* 的基础上,分别采用了表面型配对相互作用(IS配对)和同位旋依赖的接触配对相互作用(IS+IV配对)。我们发现,时间奇场一般对配对间隙的影响很小,但达到更好的协议与实验数据使用SLy 4和SLy 6相互作用,分别。当考虑时间奇场的贡献时,IS+IV对的计算比IS对的计算更能再现Sn同位素的单中子分离能。
The effect of time-odd fields of Skyrme interaction on neutron odd-even mass differences is studied in the framework of axially deformed Skyrme Hartree-Fock (DSHF)+BCS model. To this end, we take into account both the time-even and time-odd fields to calculate the one-neutron and two-neutron separation energies and pairing gaps of semi-magic Ca, Ni, and Sn isotopic chains. In the calculations, a surface-type pairing interaction (IS pairing) and an isospin dependent contact pairing interaction (IS+IV pairing) are adopted on top of Skyrme interactions SLy4, SLy6 and SkM*, respectively. We find that the time-odd fields have in general small effects on pairing gaps, but achieve better agreement with experimental data using SLy4 and Sly6 interactions, respectively. It is also shown that the calculations with IS+IV pairing reproduce the one-neutron separation energies of Sn isotopes better than those with the IS pairing interaction when the contributions of the time-odd fields are included.
