Abstract

The excitation energy of the lowest-energy superdeformed band in Pb196 is established using the techniques of time-correlated γ-ray spectroscopy. Together with previous measurements on Pb192 and Pb194, this result allows superdeformed excitation energies, binding energies, and two-proton and two-neutron separation energies to be studied systematically, providing stringent tests for current nuclear models. The results are examined for evidence of a "superdeformed shell gap."
