Double Coriolis coupling in odd-odd deformed nuclei

Double Coriolis coupling is expected to play an important role in the study of spectra, static moments and transition probabilities of odd-odd nuclei in bands with K=0sup(-+) and 1sup(-+). odd-even shift observed in case of these bands is expected to be useful in understanding the nature of nuclear forces as only the tensorial forces are likely to explain the odd-even shift. As the first step, the effect of double coriolis coupling on the moment of intertia of deformed odd-odd nuclei is studied. The computed results are compared with the experimental reports. (author)
