“…These two configurations for 17 O are: the ground state of the 16 O core coupled to the valence nucleon in a 1d 5/2 orbital, and the 16 O core in its excited 2 + state coupled to the valence neutron in a 2s 1/2 orbital. Both configurations must correspond to the ground state energy, which means that the available energy for the neutron in the 1d 5/2 orbital is different than that for the neutron in the 2s 1/2 orbital due to core excitation.…”

“…Additionally we studied (p, d) reactions on 40 Ca using the the nonlocal dispersive optical model. We have also included nonlocality consistently into the adiabatic distorted wave approximation and have investigated the effects of nonlocality on on (d, p) transfer reactions for deuterons impinged on 16 O, 40 Ca, 48 Ca, 126 Sn, 132 Sn, 208 Pb at 10, 20, and 50 MeV.…”

Explicit inclusion of nonlocality in(d,p)transfer reactions

Background: Traditionally, nucleon-nucleus optical potentials are made local for convenience. In recent work we studied the effects of including nonlocal interactions explicitly in the final state for (d,p) reactions, within the distorted wave Born approximation.Purpose: Our goal in this work is to develop an improved formalism for nonlocal interactions that includes deuteron breakup and to use it to study the effects of including nonlocal interactions in transfer (d,p) reactions, in both the deuteron and the proton channel.Method: We extend the finite-range adiabatic distorted wave approximation to include nonlocal nucleon optical potentials. Results: We find that nonlocality in the deuteron scattering state reduces the amplitude of the wave function in the nuclear interior, and shifts the wave function outward. In many cases, this has the effect of increasing the transfer cross section at the first peak of the angular distributions. This increase was most significant for heavy targets and for reactions at high energies.Conclusions: Our systematic study shows that, if only local optical potentials are used in the analysis of experimental (d, p) transfer cross sections, the extracted spectroscopic factors may be incorrect by up to 40% due to the local approximation.
