在相对论平均场理论中引入同位旋标量-矢量介子ω张量项,以208Pb为例,研究了张量项对原子核平均势场、介子场、自旋-轨道耦合势、单粒子能级的自旋-轨道劈裂和原子核壳层结构等的影响．结果发现张量项对核子平均势的影响主要表现在原子核的表面．随着张量耦合强度的增加,自旋-轨道耦合势增强,单粒子能级的自旋-轨道劈裂增大,从而导致原子核单粒子能级的壳层结构发生很大变化,传统幻数所对应的主壳消失,新的主壳出现。 In the theory of relativistic average field, a parity-vector meson ω-tensor term is introduced. Taking 208Pb as an example, the influence of tensor terms on the average potential field, the meson field, the spin-orbit coupling potential and the single-particle level Spin-orbit splitting and nucleus shell structure and so on. The results show that tensor terms on the average nuclear potential impact mainly on the surface of the nucleus. As the tensor coupling strength increases, the spin-orbit coupling potential increases and the spin-orbit splitting of the single-particle level increases, resulting in a great change in the shell structure of the single-particle level of the nucleus. The traditional magic number The corresponding main shell disappears, the new main shell appears.
