论文摘要
考虑了低能光谱中的激发状态，$^{70-76} $ ni。为此，采用表面增量相互作用的形式的配对力来解释具有资历$ν= 2 $状态的基态多重组的形成。用相邻核的质量关系描述了多重分裂分裂。随后，资历模型用于复制或预测状态的$ν= 3 $，即奇数同位素和$ν= 4 $偶数同位素。 $ 2_1^+$状态的正确帐户应允许说明状态的反向订单$ j = 4 $，$ν= 2 $和$ν= 4 $在实验中观察到。将获得的结果与$ n = 50 $的类似多重组的结构进行了比较。
Excited states in low-energy spectra in $^{70-76}$Ni are considered. To this end, pairing forces in form of surface delta interaction are employed to account for formation of the ground state multiplet with seniority $ν= 2$ states. The multiplet splitting is described with mass relations of masses of neighbouring nuclei. Subsequently, seniority model is used to reproduce or predict the states $ν= 3$ in odd-even isotopes and $ν= 4$ in even-even isotopes. Correct account of $2_1^+$ state should allow for description of reversed order of states $J = 4$ with $ν= 2$ and $ν= 4$ observed in experiment. The results obtained are compared with the structure of similar multiplets in $N=50$ isotones.
