Isovector pair correlations in analytically solvable models

Nuclear Theory 2021-01-06 v1

Abstract

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^{56}Ni can be described as anharmonic pairing vibrations. The results obtained indicate the presence of the α\alpha-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.
