摘要: 过渡区原子核的形变与准粒子占据的轨道密切相关。采用推转壳模型首次系统性地研究了奇A核⁹⁹Pd、¹⁰¹Pd和¹⁰³Pd原子核中h11/2轨道对核芯的形状驱动效应，基于Total-Routhian-Surface (TRS)方法的计算结果表明，当过渡区原子核⁹⁹Pd、¹⁰¹Pd和¹⁰³Pd中的准粒子开始占据h11/2入侵轨道时将会使原子核产生稳定的四极形变。另外，对A≈ 210 质量区近滴线核的高自旋态研究现状及今后进一步的工作也进行了概述。

The deformations of the nuclei in the transitional region are closely related to the orbitals occupied by the quasiparticles. The driving effects of the h_11/2 intruder orbitals in ⁹⁹Pd, ¹⁰¹Pd and ¹⁰³Pd were studied in the framework of the cranked shell model. Based on the total-Routhian-surface (TRS) calculations, the h_11/2 intruder orbitals might polarize the cores of ⁹⁹Pd, ¹⁰¹Pd and 103Pd to a small, but rigid quadrupole deformation,and thus collective rotational motion would develop. The aspects for the research on the high spin states of near the drip-line nuclei in A≈ 210 region as well as our future research work are also briefly reviewed.
