论文摘要
在质子数Z = 114、120和126以及中子数178 $ \ le $ n $ \ le $ 188的区域中，对张量力对壳结构进化的影响进行了系统研究。在这项调查中，我们在两种情况下，使用不同类型的Skyrme功能使用Hartree-Fock框架，具有和没有张力力。 Bardeen-Cooper-Schriefer（BCS）近似已用于治疗配对相关性。通过研究所考虑的核的结构和衰减特性，发现n = 184壳间隙通过张量相互作用增强，这取决于使用Skyrme相互作用的等值器张量耦合常数$ C_0^J $。在没有张量相互作用的情况下，此差距仅对T22，T24，T42和SLY5显着。因此，它会随T46，T64和T66消失，对于T26，T44和T62来说太弱了。毫无例外，当考虑到张量部分时，n = 184处的壳缝隙变得更加明显。
A systematic study of the effect of tensor force on the evolution of shell structure in even-even super-heavy nuclei in the region of proton numbers Z=114, 120 and 126 and in the region of neutron numbers 178 $\le$ N $\le$ 188 is presented. We use, in this investigation, the Hartree-Fock framework by means of different types of Skyrme functionals in two cases with and without tensor force. The Bardeen-Cooper-Schriefer (BCS) approximation has been used to treat the pairing correlations. By investigating structural and decay properties of nuclei under consideration, it is found that N=184 shell gap is more enhanced by the tensor interaction which depends on the isoscalar tensor coupling constant $C_0^J$ of the used Skyrme interactions. In the case without tensor interaction, this gap is significant only for T22, T24, T42 and SLy5. So, it disappears with T46, T64 and T66, and is too weak for T26, T44 and T62. Without exception, the shell gap at N=184 becomes more pronounced when the tensor part is taken into account.
