Abstract

High-spin states in the odd-odd nucleus 168^{168}Ta have been populated in the 120^{120}Sn(51^{51}V,3n) reaction. Two multi-quasiparticle structures have been extended significantly from spin 20\sim{20\hbar} to above 40{40\hbar}. As a result, the first rotational alignment has been fully delineated and a second band crossing has been observed for the first time in this nucleus. Configurations for these strongly-coupled rotational bands are proposed based on signature splitting, B(M1)/B(E2)B(M1)/B(E2) ratio information, and observed rotation-alignment behavior. Properties of the observed bands in 168^{168}Ta are compared to related structures in the neighboring odd-ZZ, odd-NN, and odd-odd nuclei and are discussed within the framework of the cranked shell model.
