摘要：

A discrete superdeformed band is found in 146Gd. Lifetime measurements yield an average quadrupole moment of 12±2 e b. A band crossing corresponding to an alignment of ≈2h{stroke} is observed at a rotational frequency of 0.65 MeV. A theoretical analysis suggests that the band has a π62v71 configuration with odd spins and odd parity. Arguments are given that the [651 1 2] and [642 5 2] single-particle states are involved in the band crossing. © 1990.
