Abstract

The quasicontinuous spectra associated with the decay of the superdeformed bands in 192,194Pb have been extracted. The rapid rise in the γ-ray intensity in these spectra for Eγ≲1.8 MeV is interpreted to arise from the dramatic increase in level density above the energy gap for even-even nuclei. This energy gap has been found to be ≈0.95(10) MeV at 6ℏ in 194Pb and ≈0.4±0.40.1 MeV at 10ℏ in 192Pb.
