摘要

The continuum-discritized coupled channel method and the glauber model are applied for the description of deuteron elastic breakup and the stripping processes,respectively.Combined with the conventional two-component exciton model for pre-equilibrium processes and the Hauser-Feshbach theory for compound process,an approach based on models is proposed to analyze the inclusive proton energy spectra of a deuteron-induced reaction.The contributions from each process to the energy spectra of the 58 Ni(d,xp) reaction are quantitatively given.The results show that this approach is able to reasonably reproduce the experimental data of the double differential cross sections,energy spectra and cross sections,although further improvements are needed.A deuteron is a loosely bound nucleus composed of a proton and a neutron,and it breaks easily when interacting with a target nucleus.Therefore,unlike nucleon-induced reactions,a deuteron-induced reaction is much more complicated.Besides the elastic and inelastic scattering processes,several reaction processes can occur.Firstly,the elastic breakup (EB)process can occur,denoted by (d,np),where the neutron and the proton are emitted separately with the target nucleus in its ground state.Also,the stripping process (STR),or so-called inelastic breakup,can occur with one nucleon released and the other interacting strongly with the target.
