Double differential cross sections of light charged particle emission in neutron induced reactions on 54,56,57,58Fe

The energy spectra and double differential cross sections of the light composite particle (deuteron, triton, helium and alpha-particle) emissions for n + 54,56,57,58Fe reaction are studied by integrating the optical model, the intra-nuclear cascade model, direct reaction theories, equilibrium reaction theory and the exciton model which included the improved Iwamoto-Harada model. Theoretical calculated results are compared with existing experimental data.
