Nuclear-structure effects in proton evaporation spectra
1990
Energy spectra and angular distributions of evaporated protons from the reaction {sup 52}Cr({sup 34}S, 2{ital p}2{ital n}){sup 82}Sr at 130 MeV were measured in coincidence with discrete {gamma} transitions. Large shifts and changes in the shape of the proton spectra were observed when high-spin states in different rotational bands are populated. They are interpreted as due to near-yrast stretched proton emission, which preferentially populates the yrast band by subbarrier protons.
