$T=1$ Pairing Along the $N=Z$ Line

Abstract

Pairing energies for the addition of two neutrons on even-even nuclei with $N=Z$ are studied. The $Z$ dependence is attributed to the number and type of orbitals that are occupied in the valence shell-model space. Properties in the region from $Z=60-100$ depend on the location of the $0g_{9/2}$ orbital.Comment: 3 pages and 2 figure
