解析可解模型中的等向量对相关
Isovector pair correlations in analytically solvable models
摘要：
给出了描述等矢量对关联的不同势的集体哈密顿量的本征解，并与实验能量进行了分析和比较。结果表明，$^{56}$ Ni周围核的等矢对关联可以用非谐配对振动来描述。结果表明，这些核中存在$α$ -粒子型关联和不同于等矢量配对的相互作用，这种相互作用也影响能量的同位旋依赖性。
英文摘要：
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 $^{56}$Ni can be described as anharmonic pairing vibrations. The results obtained indicate the presence of the $α$-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.
