Abstract

A level density formula including low-energy rotational levels for nuclei with axially symmetric deformation is tested with neutron resonance data for lanthanide and actinide nuclides. The calculations with the microscopic theory including nuclear pairing utilize deformed single particle levels of Nilsson et al. The experimental data for the actinide nuclei and the lanthanide nuclei are consistent with a theory which includes collective rotational levels. The derivation and applicability of a level density formula which includes collective rotational levels are discussed.

    As pointed out before [33] TLO invoking three resonance poles leads to a reduced spreading width and this results in a low cross section outside of the main IVGDR peak; the total integrals are in a surprisingly good accord to the TRK sum rule [89,84]. To study the A-dependence of our scheme we have tried to extend our predictions to the well documented Maxwellian averages for n-capture [70] but then we were not sure about the n-strength functions. This is why we now present in Fig. 8 gamma-decay widths predicted on the basis of Eq. (5).
