Dp. Mcnabb et al., Quasicontinuous decay spectra of superdeformed bands in Pb-192,Pb-194 and energy gaps in level density at moderate angular momenta - art. no. 031304, PHYS REV C, 6103(3), 2000, pp. 1304
The quasicontinuous spectra associated with the decay of the superdeformed
bands in Pb-192,Pb-194 have been extracted. The rapid rise in the gamma-ray
intensity in these spectra for E gamma less than or similar to 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 appro
ximate to 0.95(10) MeV at 6 (h) over bar in Pb-194 and approximate to 0.41(
-0.1)(+0.4) MeV at 10 (h) over bar in Pb-192.
