Two-nucleon high-spin states, the Bansal-French model and the crude shell model

Abstract

Recent data on two-nucleon stretched high-spin states agree well with the crude shell model predictions. For two-neutron high-spin states, the A and T linear dependence of ${B}_{2\mathrm{n}}$ in the Bansal-French model can be deduced from the A and T linear dependence of ${B}_{\mathrm{n}}$ and the crude shell model. ${7}_{2}^{\mathrm{\ensuremath{-}}}$ states in some Zn and Ge even nuclei might be two-proton states. This hypothesis should be confirmed by two-proton transfer reaction.
