Superdeformed (SD) bands in152Dy,151Dy and151Tb have been populated via the 5n, 6n and 5np evaporation channels, respectively, with the33S+124Sn reaction at 160 and 170 MeV bombarding energies. Population intensities are in good agreement with existing data for SD bands in151, 152Dy and SD yrast band in151Tb. The excited twin SD band in151Tb with the same-transitions as the band in152Dy is populated about 5 times more strongly than by the 6n evaporation channel. This might be explained in terms of competition between proton and emission out of an intermediate, excited superdeformed configuration of152Dy.

Abstract
Superdeformed (SD) bands in152Dy,151Dy and151Tb have been populated via the 5n, 6n and 5np evaporation channels, respectively, with the33S+124Sn reaction at 160 and 170 MeV bombarding energies. Population intensities are in good agreement with existing data for SD bands in151, 152Dy and SD yrast band in151Tb. The excited twin SD band in151Tb with the same-transitions as the band in152Dy is populated about 5 times more strongly than by the 6n evaporation channel. This might be explained in terms of competition between proton and emission out of an intermediate, excited superdeformed configuration of152Dy.File in questo prodotto:
