Low- Z boundary of the N=88 –90 shape phase transition: Ce148 near the critical point
Excited states of the neutron-rich nucleus 148Ce have been populated by neutron-induced fission of a 235U target. Its electromagnetic decays were studied by means of γ-ray coincidence spectroscopy with fast- timing capabilities. Lifetimes of the 2+1 and 4+1 states of 148Ce were obtained and their E2 decay rates deduced. The B4/2=B(E2 ; 4+1→2+1)/B(E2 ; 2+1→0+1) ratio indicates that 148Ce is a transitional nucleus while the N=88/90 shape phase transition evolves into a gradual change of nuclear deformation for proton numbers Z<60.
