Limits of observable proton-emitting nuclei between theN=82andZ=82shell closures

Abstract

The regular systematic behavior of ${Q}_{\mathrm{p}}$ values is analyzed to provide a basis for estimating $Q$ values for as yet unknown proton and $\ensuremath{\alpha}$ decays. These estimates are used in predicting partial half-lives for proton and $\ensuremath{\alpha}$-particle emission from states in Ta, Re, Ir, and Au nuclei beyond the proton drip line. The implications of these predictions for further experimental study in this region are discussed.
