Abstract

A discussion of (d, p) stripping reactions into the continuum is given. Special attention is paid to a comparison between the corresponding neutron elastic scattering by the same target nucleus near a resonance. We study the neutron wave function in the neighbourhood of a resonance using different models. These wave functions turn out to be rather different, which can influence the resonance line shape in the (d, p) stripping spectrum. This is illustrated in the case of 15N(d, p)16N(unbound). Thus, under certain conditions, where the contributions of the interior region to the DWBA integral can be large, a very good knowledge of neutron wave functions is found to be necessary for an accurate description of the process. Furthermore, the reaction 208Pb(d, p)209Pb(unbound) at almost “sub-Coulomb” energies (Ed = 12 MeV) is investigated within the same models, where, because of the Coulomb barrier, the influence of the interior region is small.
