- Abstract
The Asymmetric Rotor Model of Davydov-Filippov has been employed to compute the B(E2) branching ratios from I = 4 level of Kπ = 2+ gamma vibrational band in even-even deformed nuclei covering rare earth and actinide regions. The present results are compared with known experimental values and other available phenomenological and microscopic models. The computed DF values show a better agreement with experimental values as compared to the microscopic model values. The present work indicates that it favours the rigid shape of the nucleus at the excitation energies more than 1 MeV. It also provides an evidence for the inference that the low lying Kπ = 2+ mode is the collective γ-mode of the nuclear shape vibrations which contradicts the view point of Zawischa et al.
