Description

Eight superdeformed bands have been observed in the nuclei 147,148Eu. Some of these are identical to bands in the Z+1 nuclei 148,149Gd, and are interpreted as having the same single-particle configurations with the exception of a hole in one of the [301]1/2 proton orbitals. Some of the bands in 147Eu exhibit either upbends or downbends in their moments of inertia which are related to the crossing of π61 and π63 proton intruder configurations. These results constitute the first evidence of this crossing. copyright 1998 The American Physical Society
