The eigensolutions of the collective Hamiltonian with different potentials suggested for description of the isovector pair correlations are obtained, analyzed and compared with the experimental energies. It is shown that the isovector pair correlations in nuclei around [Formula: see text]Ni can be described as anharmonic pairing vibrations. The results obtained indicate the presence of the [Formula: see text]-particle type correlations in these nuclei and the existence of the interaction different from isovector pairing which also influences on the isospin dependence of the energies.

可解析模型中的等向量对相关性

获得了具有不同势能的集体哈密顿量的本征解，用于描述等向量对相关性，并与实验能量进行了分析和比较。结果表明，[公式：见正文]Ni周围的原子核中的等向量对相关性可以描述为非谐配对振动。获得的结果表明在这些原子核中存在[公式：参见文本]-粒子类型相关性，并且存在与等向量配对不同的相互作用，这也影响能量的同位旋依赖性。
