Properties of proton drip-line nuclei at thesd-fp-shell interface

Abstract

Properties of proton-rich nuclei at the sd-fp-shell boundary with 37≤A≤48 are investigated within the framework of the nuclear shell model. Predicted binding energies, one- and two-proton separation energies, and β-end-point energies are presented. Half-lives associated with one- and two-proton emissions are compared with β decay, and it is determined that the best candidates for the observation of correlated two-proton emission are ${}_{}{}^{38}{}_{}{}^{}\mathrm{Ti}$ and ${}_{}{}^{45}{}_{}{}^{}\mathrm{Fe}$. The predicted branching ratios for β decay as a function of excitation energy in the daughter nucleus are shown. Where available, β-decay half-lives are compared with experiment and are found to be in overall good agreement. © 1996 The American Physical Society.
