Valence-mirror symmetry in the first g9/2 subshell for semi-magic nuclei
The Ni42/Mo50, Ni44/Ru50, Ni46/Pd50 and Ni48/Cd50 valence-mirror pairs have been studied using valence-mirror energy differences for the first time. Valence-mirror symmetry is discussed based on a systematic analysis of the valence-mirror energy differences and supported by shell-model calculations. Mass scaling of the energy spacings in 74Ni/96Pd/128Pd and 76Ni/98Cd/130Cd has been investigated, focusing on the and spacings. In particular, simple schematic shell-model calculations using a interaction have been performed for 76Ni and 130Cd to study the structural evolution with increasing spin.
