Abstract

High-spin states in [Formula Presented] were populated using the fusion-evaporation reactions [Formula Presented] at a beam energy of 125 MeV and [Formula Presented] at a beam energy of 143 MeV. The Gammasphere array in conjunction with ancillary detector systems allowed for the identification of a superdeformed rotational band in [Formula Presented] which was firmly linked to low-spin yrast states. Using directional correlations of oriented states, a spin-parity assignment of [Formula Presented] to the band head was possible. The average quadrupole moment of the band is measured to be [Formula Presented] The characteristics of the band are compared to neighboring nuclei and predictions of different mean-field theories.
