The isovector and isotensor energy differences between yrast states of isobaric multiplets in the lower half of the pf region are quantitatively reproduced in a shell model context. The isospin nonconserving nuclear interactions are found to be at least as important as the Coulomb potential. Their isovector and isotensor channels are dominated by J=2 and J=0 pairing terms, respectively. The results are sensitive to the radii of the states, whose evolution along the yrast band can be accurately followed.
在壳模型框架下，定量再现了pf区域下半部分等压多重态基态之间的同位旋矢量和同位旋张量能量差。发现同位旋不守恒的核相互作用至少与库仑势一样重要。它们的同位旋矢量和同位旋张量通道分别由J = 2和J = 0配对项主导。结果对态的半径敏感，其沿基态带的演化可以精确跟踪。
