Highest spin discrete levels in Ce-131,Ce-132: Spin generation near the mesoscopic limit

Abstract
The three superdeformed (SD) bands in Ce-132 and the two SD bands in Ce-131 have been extended to higher spin, following experiments with the EUROBALL IV spectrometer. The two SD bands in Ce-131 have been linked together. However, despite the relatively high population intensity of the bands (up to 5% of the respective channel), it has not been possible to unambiguously link any of the five SD bands into the low-spin, normally deformed structures of Ce-131,Ce-132. At the highest spins (> 60h), some of the bands exhibit the characteristic behavior of smooth band termination, i.e., energetically costly angular-momentum generation near the finite mesoscopic limit. Configuration-dependent cranked Nilsson-Strutinsky calculations have been... (More)

Configuration-dependent cranked Nilsson-Strutinsky calculations have been performed to suggest single-particle configurations for the SD bands and to investigate the possibility of termination in these bands.
