Odd mass nuclei in the mass regions 100 ≤ A ≤ 130 from a vertical perspective within the NpNn scheme

Abstract

We present here the symmetrical level schemes of odd mass pseudo-mirror nuclei for the first time within NpNn scheme. Pseudo-mirror nuclei having particle-hole symmetry are to reflect similar experimental structures, where the NpNn quantity is an indicator of the pronounced symmetry. In the light of available data, the 125Cs–107Rh, 123Cs–109Rh, 127La–105Tc, 127Ce–105Mo, 123Ba–109Ru and 131Nd–101Zr nuclei have been analyzed in a vertical perspective with in the pseudo-mirror nuclei framework. The analysis of level schemes of the nuclei of interest revealed that almost degenerate quadrupole electric transitions from equal spin-parity states in even–odd and odd–even pseudo-mirror nuclei.
