Transitions probabilities up to I = 36{sup +} in {sup 160}Yb

Abstract

During the past dozen years or so, numerous groups have worked on the properties of the ytterbium nucleus, 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 that it reflects the intrinsic part of the wave function, and hence provides an indication of the collectivity. This paper presents the results from recent Doppler broadened line shape measurements in {sup 160}Yb at very large rotational frequencies of {Dirac_h}{omega} {approx} 0.36 - 0.50 MeV (I = 22{sup +} - 36{sup +}). (author) 16 refs., 3 figs.
