Evidence for highly deformed bands in Sm-133(62)71 - art. no. 054314

Excited states of the Sm-133 nucleus have been populated to high spin via t he Ru-96(Ca-40, 2pn) reaction. Rotational structures have been observed and their characteristics studied by examination of their dynamic moments of i nertia and alignment gains. These experimentally derived quantities have be en compared with theoretical calculations from both standard cranked shell and self-consistent total Routhian surface calculations. The discovery of a new coupled band within the Sm-133 nucleus has lead to the reassignment of the configuration of one of the previously identified bands. The new calcu lations predict strong polarization effects for different configurations, w hich result in quadrupole deformations that vary from beta(2)similar to 0.2 8 to greater than or equal to 0.38.
