Abstract: The non- equidistant space model (non-ESM) for two-component state densities has been modified to include different correction parameters. The calculated results have been used with neutron induced reaction with 56Fe target nuclei. The comparisons with other theoretical and experimental results show a very good agreement at excitation energy less than 15 MeV. The modified state density has been applied to calculate the cross-sections of emitting a complex particles in 98Mo (n, n+p) 97Nbm and 98Mo (n, 4He) 96Zr reactions for different incident neutron energies. Furthermore, the results are compared with the available experimental results of EXFOR. It was found the weaker probability of emitting complex particles comes from weaker primary pre-equilibrium emission due to high binding energies of complex particles. Different stages of probabilities for neutron induced complex particles emissions have been studied to evaluate the depletion factor DF that weakly contributed from the direct or PE processes in (neutron +98Mo) reaction by consume the flux in complex emission particles, (n+p) and (4He).
