A geometry dependent hybridipre-equilibrium emission model with conservation of angular momentum

Inclusion of the angular momentum conservation in the Geometry Dependent Hybrid (GDH) pre-equilibrium emission subroutine of the Hauser-Feshbach code STAPRE is discussed. The consistency of the statistical model nuclear level density and the equivalent particle-hole state density have been achieved following a unitary use of an energy dependent level density parameter. GDH and Hauser-Feshbach calculations for proton emission spectra from 15 MeV neutron induced reactions on 46Ti, 48Ti isotopes have given a first validation of the present approach. (authors)
