ISOSPIN-FORBIDDEN BETA-DELAYED PROTON EMISSION

Shell-model calculations have been carried out for isospin-forbidden -delayed proton emission for 1s-0d-shell nuclei. The process in which a nucleus near the proton drip line decays by a superallowed transition to the isobaric analog state in the daughter nucleus is considered. The first complete set of calculations for the subsequent isospin-forbidden particle decay of the isobaric analog state is presented. The decay channels considered include the processes of single-proton, sequential two-proton, direct two-proton, and ± decay. The calculations reproduce the known data and suggest further experiments. © 1990 The American Physical Society.
