U(6 mod 10) supersymmetry in the Ni isotopes

Abstract

Supersymmetry calculations are performed for the Ni isotopes within the framework of the IBM using the concept of dynamic symmetries for the U(5)*SUF(2) limit of the graded Lie group U(6 mod 10). The excitation spectra and the electric quadrupole transitions of the isotopes belonging to the same representation of the graded Lie group and the spectroscopic factors for single-particle pick-up reactions between such isotopes are calculated and compared with experimentally observed values. The results are encouraging.
