- Abstract
- Total level densities and state densities up to 40 MeV of excitation
energy are calculated combinatorially for the systematics of Pb nuclei using
independent nucleons in the realistic single particle spectra. These
combinatorial level densities are well fitted by GBF, both for doubly closed
shell nucleus Pb-208 and away from the shell closure. The corresponding GBF
parameters exhibit smooth behavior with the change of the neutron number N,
having pronounced extrema at the double shell closure. The GBF fit to the
combinatorial results is compared with the fit of standard Bethe formula (BF)
and of the Ignatyuk formula. (C) 1997 Elsevier Science B.V. [References: 44]
