Description: Recoil-distance measurements of lifetimes of high-spin states of /sup 160/ /sup 161/Yb are described. While the results for the ground band of /sup 160/Yb are not inconsistent with centrifugal stretching, the addition of one or more quasineutrons seems to cause a reduction in collectivity which depends on frequency but not, for the case examined, on the type of quasineutron. 9 references.
