Abstract

Excited states in the light lead nucleus, Pb-182, have been observed for the first time, by means of the recoil-decay tagging technique. A rotational band has been observed which has features in common with bands attributed to a prolate configuration in the heavier neutron deficient lead nuclei, Pb184-188. A variable moment of inertia fit to the states in this band suggests that the prolate minimum has risen significantly in energy compared to the next even lead nucleus, Pb-184. This constitutes firm evidence for the minimization of this configuration with respect to the spherical ground state around N = 103.
