Ground-State Bands in Neutron-Rich Even Te, Xe, Ba, Ce, Nd, and Sm Isotopes Produced in the Fission ofCf252

Abstract
We present experimental results on the ground-state bands of heavy even-even nuclei produced in the primary fission of Cf252. Experimental values for the energy levels and lifetimes range from those typical of spherical nuclei to those associated with permanently deformed nuclei.
