| Research Abstract |
A theoretical model analysis was performed for deuteron-induced reactions on Li up to 100MeV, which is one of the candidate reactions used as an accelerator-driven neutron source. The inclusive nucleon spectra from deuteron breakup reactions on Li are analyzed by using the continuum discretized coupled channels theory for elastic breakup process, the Glauber model for nucleon stripping process, and the moving source model for preequilibrium and evaporation processes. The calculation reproduces a prominent bump observed in experimental nucleon emission spectra at forward angles quite well. The present analysis clarifies that the stripping process is more dominant than the elastic breakup process in deuteron breakup reactions on Li.
