• Role of γ−g band mixing in triaxial vs. deformed nuclei

Recently, we illustrated the use of the ${\gamma}$–g absolute B(E2) values in the Davydov–Filippov model (DFM), instead of the ${\gamma}$−g B(E2) ratios,for analysing the spectral features of the (${\gamma}$${\le}20°) deformed nuclei. Here, we illustrate the application of the absolute {\gamma}−g B(E2) values to the triaxial (γ{\ge}20°) nuclei to seek the new role of the {\gamma} variable in these nuclei, and to derive the underlying physics. The decrease of the absolute {\gamma}−g B(E2) value for {\gamma}$${\ge}$20°, instead of an increase observed for ${\gamma}$${\le}20° deformed nuclei is explained. The increase of B(E2, 2_γ − 0^+$$_1$ ) in spite of the negative band mixing parameter, for deformed nuclei, reveals a new view of the band mixing angle, in contrast to its role for the triaxial nuclei. The three moments of inertia in DF model, for ${}^{158}$Dyand ${}^{120}$Xe display their degree of triaxiality.
