Inclusive proton emission from deuteron-induced reactions on various nuclear targets at an incident energy of 100 MeV are analyzed using the CDCC theory for elastic breakup process and the Glauber model for neutron stripping process. Moreover, the phenomenological moving source model is used to estimate evaporation and pre-equilibrium components in inclusive spectra. The calculation reproduces fairly well a prominent bump in experimental spectra for light and medium nuclei at forward angles of less than 20, whereas the calculation underestimates the bump component as target atomic number increases. The underestimation is likely to be attributed to the fact that the eikonal approximation used in the Glauber model becomes worse due to strong Coulomb interaction. It is shown that the Glauber model calculation for neutron stripping process leads to improvement of this discrepancy by substituting the eikonal phase shift for the quantum phase shift.
