Abstract

Excited states in the light lead nucleus, [Formula Presented] 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, [Formula Presented] 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, [Formula Presented] This constitutes firm evidence for the minimization of this configuration with respect to the spherical ground state around [Formula Presented].
