论文摘要

通过简单但简单的物理模型提出和研究了一种评估一般变形对库仑直接贡献对等速剂模拟状态(IAS)能量的影响的公式。玩具模型在测试案例中对显微镜变形的Hartree-fock-bogolyubov(HFB)计算提供了合理的说明,并在预测未知IAS能量时提供了指导。因此,用于预测IAS能量的变形的HFB计算是针对几个中子缺陷的中子质量和重核进行的,现在计划通过实验研究。

A formula to evaluate the effects of a general deformation on the Coulomb direct contribution to the energy of the Isobaric Analog State (IAS) is presented and studied via a simple yet physical model. The toy model gives a reasonable account of microscopic deformed Hartree-Fock-Bogolyubov (HFB) calculations in a test case, and provides a guidance when predicting unknown IAS energies. Thus, deformed HFB calculations, to predict the IAS energies, are performed for several neutron-deficient medium-mass and heavy nuclei which are now planned to be studied experimentally.
