Binding energies of proton-rich nuclei in the vicinity ofSn100

Shell-model calculations suggest that binding energies of several proton-rich nuclei in the vicinity of ${}_{}{}^{100}{}_{}{}^{}\mathrm{Sn}$ differ appreciably from the estimates given in the most recent Mass Tables. We give improved estimates, which should be of considerable interest to researchers at GSI and elsewhere who are studying β-decay and β-delayed proton emission from these nuclei.
