Inclusive proton emissions from deuteron-induced reactions on 9Be, 12C, 27Al, 58Ni, 93Nb, 181Ta, 208Pb, and 238U at an incident energy of 100 MeV are analyzed using the continuum discretized coupled-channels theory for the elastic-breakup process and the Glauber model for the neutron-stripping process in order to investigate deuteron-breakup processes over a wide range of target mass numbers. The effects of Coulomb interactions are taken into account to give a proper description of proton emissions at forward angles. Moreover, the phenomenological moving-source model is used to estimate evaporation and preequilibrium components in inclusive (d,xp) spectra. The calculation reproduces fairly well a prominent bump observed around half the incident energy in experimental (d,xp) spectra for light and medium nuclei at forward angles of less than 20 whereas the calculation underestimates the bump component as the target atomic number increases. The underestimation is likely due to the fact that the eikonal approximation used in the Glauber model becomes worse due to strong Coulomb interactions. It is shown that the Glauber-model calculation for the neutron-stripping process leads to an improvement of this discrepancy by substituting the eikonal phase shift for the quantum phase shift given by the optical-model calculation.
