During the past dozen years or so, numerous groups have worked on the properties of the ytterbium nuclei and we at Oak Ridge have been actively involved in the study of many of these nuclei. We have concentrated on lifetime measurements of their high-spin states because it is from the lifetime of a state that one can determine Q{sub t}, the transition quadrupole moment. The importance of obtaining a Q{sub t} value is in that it reflects the intrinsic part of the wave function and, hence, provides an indicator of the collectivity. This paper presents the results from recent Doppler broadened line shape measurements in {sup 16O}Yb at very large rotational frequencies of {bar H}{omega}{approx}0.36 {minus} 0.50 MeV (I = 22{sup +}{minus}36{sup +}).
