Abstract
Relative electromagnetic transition rates in 165Lu94 have been measured to high spin (I≤ 63 2) for the two signature components of a band built on a πh 11 2 shell-model state. M1 transitions are observed through two band crossings. A DSAM measurement indicates that full collectivity persists for the πh 11 2 configuration up to I ≤ 53 2 and that for higher values of I a loss of collectivity could explain the observed increased values of B(M1, I → I-1)/B(E2, → I-2). The effects of alignment, shape changes and rotationally induced deoccupation of antialigned configurations are discussed. In the measured values of the ratio of transition quadrupole moments Q1/Q2 the influence of the vi 13 2 alignment is observed for the first time. The data are discussed within the context of triaxial nuclear deformation. Comparisons are made with the nuclei 161,163Lu.
