摘要

在本文中，作者根据玻尔-莫特森几何集合模型（GCM）的惯性矩表达式，提出了一个新颖的四参数公式。该公式与所考虑的所有原子核的实验数据非常吻合。还将推导出一些关键量，如旋转频率、运动惯性矩和动力惯性矩，并研究它们随自旋的变化。我们提出的四参数模型还将与可变惯性矩模型和最近提出的β拉伸模型进行比较。文中还将介绍各种 ΔI=1 和 ΔI=2 能量交错指数，并将其与实验指数进行比较。

A novel four parameter formula for the rotational spectra of even-even nuclei

In this article, the authors presents a novel four parameter formula based on developing an expression for the moment of inertia in terms of Bohr-Mottelson Geometric Collective Model (GCM). The formula provides an excellent agreement with the experimental data for all nuclei under consideration. Some key quantities will also be derived such as the rotational frequency, the kinematic and dynamical moment of inertia, and their variation with spin will be investigated. A comparison between our proposed four parameter model with both the variable moment of inertia model, and the recently proposed β-stretching model is also presented. Various

Δ I = 1

and

Δ I = 2

energy staggering indices will be presented and compared to the experimental counterpart in the paper.
