Description

Excited states in 167Ta and 168Ta, populated in the 142Nd(30Si, pxn) reaction were investigated using the ESSA30 array with 29 Compton-suppressed Ge detectors. Several rotational decay sequences are identified and for the first time a high-spin level scheme is established for these nuclei. The results for 167Ta are discussed in comparison with existing data in the neighbouring nuclei and with cranked shell model calculations. The possible intrinsic structure and its consequences for the yrast band in 168Ta are also briefly discussed. (orig.)
