Cross sections for multistep direct neutron scattering on niobium Original Research Article

Inelastic cross sections for multistep direct neutron scattering on 93Nb have been calculated at incident neutron energies of 20 MeV and 26 MeV. The enhanced non-DWBA matrix elements involving the biorthogonally conjugated wave functions were used. The results reveal significant contributions from two-, three- and four-step reactions in agreement with experiment.
