Abstract

The structure in the -delayed proton spectra of the precursors Dyg66147, Erg68149, and Ybg70151 is analyzed within the framework of a doorway-state model. Indications from -ray decay studies, strength-function measurements, and calculations of state densities and Gamow-Teller strength distributions, lead us to suggest that some of the observed proton transitions arise from the preequilibrium decay of doorway states populated in + decay or electron capture.
