Deformation-dependent Tamura-Udagawa-Lenske multistep direct model
- Belgonucleaire, B-2480 Dessel (Belgium)
The multistep direct TUL model has been extended in order to account for nuclear deformation. The new formalism was tested in calculations of neutron emission spectra from the {sup 232}Th(n, xn) reaction. These calculations include vibration-rotational coupled channels for the inelastic scattering to low-lying collective levels, ''deformed'' multistep direct (MSD) for inelastic scattering to the continuum, multistep compound, and Hauser-Feshbach with advanced treatment of the fission channel. Prompt fission neutrons were also calculated. The comparison with experimental data shows clear improvement over the ''spherical'' MSD calculations and JEFF-3.1 and JENDL-3.3 evaluations. Similar calculational results have been obtained of neutron emission spectra from the stable deformed nuclei {sup 181}Ta and {sup 184}W.
