Abstract
Three rotational bands have been observed up to spin I approximately=50 h(cross) in 160Er. The band sequences exhibit regular energy spacings between levels characteristic of prolate collective rotation except for certain states near 50 h(cross) where there is evidence for near-yrast aligned single-particle states. The phase boundary between prolate collective and oblate non-collective rotation in the light Er isotopes is summarised.Keywords
