Abstract

A discrete superdeformed band has been found in 146Gd. Lifetime measurements yielded an average quadrupole moment of 12±2 eb. A band crossing corresponding to an alignment of ≈ 2 ħ occurs at a rotational frequency of 0.65 MeV. A theoretical analysis suggests that the band has a π62ν71 configuration. Arguments are given that the [651 12] and [642 52] single-particle states are involved in the band crossing.
