摘要: 原子核中单粒子谱的自旋和赝自旋对称性对核结构的研究具有重要意义。本文基于相对论平均场理论，以¹³²Sn，_∧¹³³Sn，及_2∧¹³⁴Sn为例，研究了∧超核中单∧谱和单中子谱的自旋和赝自旋对称性。研究发现，单∧谱的自旋对称性保持得相当好，与实验观测一致；而其赝自旋对称性只是近似保持，与核子谱的情况类似。此外，还研究了∧超子对中子谱的杂质效应，发现∧超子使中子谱的自旋对称性变差，赝自旋对称性变好。

Spin and pseudospin symmetries in the single-particle spectra of atomic nuclei are of great significance for the study of nuclear structure. In this work, taking ¹³²Sn, _∧¹³³Sn, and _2∧¹³⁴Sn as examples, the spin and pseudospin symmetries in ∧ hypernuclei are studied by using the relativistic mean-field model. For the single-∧ spectra, results show that the spin symmetry maintains well while the pseudospin symmetry is approximately conserved. Besides, as impurities, the ∧ hyperons worsen the spin symmetry of single-neutron spectra while improve the pseudospin symmetry.

Spin and pseudospin symmetries in the single-particle spectra of atomic nuclei are of great significance for the study of nuclear structure. In this work, taking ¹³²Sn, _∧¹³³Sn, and _2∧¹³⁴Sn as examples, the spin and pseudospin symmetries in ∧ hypernuclei are studied by using the relativistic mean-field model. For the single-∧ spectra, results show that the spin symmetry maintains well while the pseudospin symmetry is approximately conserved. Besides, as impurities, the ∧ hyperons worsen the spin symmetry of single-neutron spectra while improve the pseudospin symmetry.
