Abstract
Evidence is presented for the existence of odd-even staggering in K− rotational bands (with K>0) of odd-odd nuclei in the rare-earth and actinide regions. Coriolis-coupling calculations have been carried out for rotational bands in Tm168, Lu176, Ta182, and Re182. With these calculations, we are able to reproduce the odd-even staggering observed in these nuclei. In particular, the unusually strong staggering observed in the K=2+ and 4− bands of Re182 can be understood. Unusual features in the wave functions of some bands reflect the importance of couplings due to terms other than Coriolis in the Hamiltonian.Keywords
