Query: 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. We apply our method to (d,p)
reactions on 16O, 40Ca, 48Ca, 126Sn, 132Sn, and 208Pb at 10, 20 and 50 MeV.
  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.
