The one- plus two-body isospin non-conserving nuclear interactions, namely the isovector and isotensor ones, are included in the prediction of the energies of the ground state and the low-lying states of the fp shell nuclei using spectral distribution theory. This in turn is used to calculate the linear term in the isobaric mass-multiplet equation and the predictions are then compared with experimental values after the addition of the Coulomb contribution. The agreement is found to be good as observed for sd shell nuclei earlier. One also sees that in this method the contribution to the linear term comes almost completely from the one-body isovector Hamiltonian, resulting in a huge simplification of the problem.

谱分布理论框架下fp-壳核的等压质量多重方程中的线性项

一加二体同位旋非守恒核相互作用，即等向量和等张量相互作用，包含在使用谱分布理论预测fp壳核的基态和低位态能量中。这反过来用于计算等压质量多重方程中的线性项，然后在添加库仑贡献后将预测值与实验值进行比较。正如之前对 sd 壳核所观察到的那样，该一致性被发现是好的。人们还看到，在这种方法中，对线性项的贡献几乎完全来自一体等向量哈密顿量，从而大大简化了问题。
