¹⁰¹Pd的能级结构研究以及与其邻近核素的系统性对比

摘要: 在本工作中，我们主要研究了¹⁰¹Pd核中 \nu_11/2 带的能级结构，并与临近同位素相对应的能级结构进行了对比。研究发现在Pd同位素链，即 N\!= \!Z\! =\! 50 的壳附近，三轴形变的演变符合很好的系统性，即从小的不稳定形变逐渐演变为稳定的长椭形变。同时，我们也做了总势能面(TRS)随着原子核转动频率以及中子数变化的系统计算，结果也支持该核区不稳定三轴形变演化的规律。

Abstract: The present work aims at the structural investigation of the \gamma- levels in \nu h_11/2 band of ¹⁰¹Pd, and its comparison with the neighboring Pd-isotopes. Theoretical investigations performed in the vicinity of Pd-isotopes i.e., around N\!=\!Z\!=\!50 shell closures have described the systematic well, indicating an evolution of shape alongwith involvement of triaxiality. The deformation studies in the vicinity of Pd-isotopes around shell closures have predicted the shape change from small deformation to more deformed prolate shapes. The comparison of Total Routhian Surface (TRS) calculations performed in the present work have also suggested the inclusion of small amount of triaxiality as a function of increasing rotational frequency and neutron number, pointing towrads the \gamma- softness present in the nuclei.
