Abstract

The high-spin structure of the nucleus ¹⁸³Re has been studied following the ¹⁷⁶Yb(¹¹B,4n) reaction. High-K, multi-quasiparticle excitations compete with collective rotation in the formation of the yrast and near-yrast structures. Broken-pair (i_13/2)² excitations (t-bands) play a dominant role, generating considerable angular momentum both along and perpendicular to the prolate symmetry axis. The stability of axially symmetric, prolate shapes is explored through comparisons with potential-energy-surface calculations. The possible onset of oblate rotation at high angular momentum is discussed.
