Abstract
The configuration-dependent cranked Nilsson-Strutinsky model is used to study the band structures in La-131. Shape coexistence and band termination are investigated for several configurations. The calculations indicate that La-131 is a gamma-soft nucleus. The theoretical results are compared with experimental data. The calculated pi( h(11/2))(2) circle times nu( h(11/2))(8) configuration with (pi, alpha) = ( +, - 1/2) shows very good agreement with the experimental band observed to highest spin. The termination of this band is not favored, i. e. a relatively large energy is required to build the highest spin states in the band.
