Examining the effect of nonlocality in $(d,n)$ transfer reactions

Abstract

Background: In the last year we have been exploring the effect of the explicit inclusion of nonlocality in (d,p) reactions. Purpose: The goal of this work is to extend previous studies to (d,n) reactions, which, although similar to (d,p), have specific properties that merit inspection. Method: We apply our methods (both the distorted wave Born approximation and the adiabatic wave approximation) to $(d,n)$ reactions on ${}^{16}$O, ${}^{40}$Ca, ${}^{48}$Ca, ${}^{126}$Sn, ${}^{132}$Sn, and ${}^{208}$Pb at $20$ and $50$ MeV. Results: We look separately at the modifications introduced by nonlocality in the final bound and scattering states, as well as the consequences reflected on the differential angular distributions. The cross sections obtained when using nonlocality explicitly are significantly different than those using the local approximation, just as in (d,p). Due to the particular role of Coulomb in the bound state, often we found the effects of nonlocality to be larger in (d,n) than in (d,p). Conclusions: Our results confirm the importance of including nonlocality explicitly in deuteron induced reactions.
