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.

变形核中的等压模拟态能量：玩具模型

通过一个简单而物理的模型，提出并研究了一个公式，用于评估一般变形对库仑对等压模拟状态 (IAS) 能量的直接贡献的影响。玩具模型对测试案例中的微观变形 Hartree-Fock-Bogolyubov (HFB) 计算给出了合理的解释，并在预测未知的 IAS 能量时提供了指导。因此，对几种缺乏中子的中等质量和重核进行变形 HFB 计算，以预测 IAS 能量，现在计划对这些核进行实验研究。
