Analysis of reaction modes of low energy reactions of deuterons with (56)Fe and (27)Al nuclei
Abstract
Measurements of deuteron-induced cross sections have been made for targets of 27Al and 56Fe. Reactions studied included elastic scattering, inelastic scattering, (d,p), (d,n) and (d,/alpha). No evidence was found for either (d,3H) or (d,3He) at the two bombarding energies (5 and 7 MeV) for either target. An optical model analysis was completed for the elastic scattering at both energies for each target. A particular effort was made to cover a large angular range (10o to 140o) with small errors. From the optical model analysis, reaction cross section values are derived. Spectra for (d,p), (d,n) and (d,/alpha) are compared with Hauser-Feshbach calculations. The (d,p) and (d,n) spectra show evidence for both stripping reactions and break-up reactions. Values for the fraction of the reaction cross section, which is due to compound nuclear reactions, are derived. Comparison with values of this parameter at higher energies derived using a different technique is presented. Some systematics of the break-up cross section are discussed.
