我们在扩展的核密度泛函理论（DFT）中研究了等压多重态质量方程（IMME），该方程包括了同位旋对称性破缺（ISB）接触项和粒子-空穴通道中的质子-中子混合。我们专注于轻原子核中的等压三重态，我们描绘的贡献等矢量和等张量IMME系数来自电磁，isoscillation，和ISB项的功能。我们比较DFT结果可用的从头计算，以评估和量化的作用，多体ISB的贡献。目的是阐明有限核中ISB效应的起源，并试图解开强作用力和库仑作用力的纠缠效应。
We study Isobaric Multiplet Mass Equation (IMME) within the extended nuclear Density Functional Theory (DFT) that includes isospin-symmetry-breaking (ISB) contact terms and proton-neutron mixing in the particle-hole channel. We focus on isobaric triplets in light nuclei and we delineate contributions to isovector and isotensor IMME coefficients coming from the electromagnetic, isoscalar, and ISB terms of the functional. We compare the DFT results to the available ab initio calculations, so as to evaluate and quantify the role of many-body ISB contributions. The aim is to elucidate the origins of the ISB effects in finite nuclei and to attempt disentangling effects of the strong and Coulomb forces.
