摘要：
Multistep direct cross sections including the contribution of incoherent particle-hole and collective excitations in the continuum, are calculated and combined with multistep compound and compound nucleus cross sections to give a complete description of neutron inelastic scattering by niobium at incident energy of 14.1 MeV. The multistep direct reactions are enhanced by using the non-DWBA matrix elements that include the biorthogonally conjugated distorted waves. The results reveal contributions from two- and three-step reactions in agreement with experiment.
