Description
Considering its weakly-bound nature, a complete description of deuteron-induced reactions remains a challenging problem for theoretical studies. To examine this problem, we perform a systematic analysis of inclusive nucleon emission cross sections for deuterons incident on a wide range of nuclei at different energies up to 100 MeV. The local-energy approximation to the post form DWBA is used to calculate the elastic and nonelastic breakup cross sections [1,2]. The breakup cross sections are integrated into the EMPIRE nuclear reaction code [3] in order to take into account the pre-equilibrium and equilibrium decay of the three compound nuclei formed in the reaction. Theoretical double differential and integrated nucleon emission cross sections are compared with the experimental ones. Our investigations demonstrate a general good agreement between the theoretical and experimental integrated cross sections. The comparisons of the experimental data with the calculated double differential cross sections show that the general behavior of the experimental spectra is reproduced at small angles and for the lighter systems, but that systematic discrepancies between the calculations and the data occur for heavier targets. Possible reasons for the disagreements are discussed.
