摘要

我们用轴对称形状的四极-八极集体模型研究了不同Th和Ra同位素的激发态。在这个模型中,我们使用核物理学中最常用的势:伍兹-撒克逊势。在此基础上对模型进行扩展,可以很好地描述由四极-八极变形引起的激发态。在这项工作中,必要的哈密顿量在合适的碱基上对角化,以产生候选核的产态。这个过程还需要优化,这是使用机器学习方法对每种同位素完成的。研究结果和结果经过仔细检验,并与实验值进行对比。

Machine learning based study of collective quadrupole–octupole excitations

We use the collective quadrupole–octupole model of axial symmetric shapes to study excited states in different Th and Ra isotopes. In this model, we use one of the most commonly used potentials in nuclear physics: Woods–Saxon potential. Extending this model based on the potential suggested is able to describe excited states due to quadrupole–octupole deformations satisfactorily. In this work, the necessary Hamiltonian is diagonalized in suitable bases to yield states of the candidate nuclei. This procedure also necessitates optimization, which is done using machine learning methods for each isotope. The findings and outcomes are carefully examined and contrasted with experimental values.
