Abstract

Electromagnetic reduced transition probabilities B(E2) and B(M1) calculated by using the PSM (Projected Shell Model) code are used to study the back-bending phenomenon in 157,158Er isotopes. As a result, two great drops in the B(E2)/B(M1) ratio were observed in spins 12 ħ and (37/2) ħ for the 158Er and the 157Er isotopes, respectively, which coincident exactly with the inertia change versus rotational frequency in the usual back-bending plots for these isotopes.
