Abstract

To investigate the possible X(5) character of 122Ba, suggested by the ground-state band energy pattern, the lifetimes of the lowest yrast states of 122Ba have been measured, via the recoil distance Doppler-shift method. The relevant levels have been populated by using the 108Cd(16O,2n)122Ba and the 112Sn(13C,3n)122Ba reactions. The B(E2) values deduced in the present work are compared to the predictions of the X(5) model and to calculations performed in the framework of the IBA-1 and IBA-2 models.
