The change in mass of a nucleon, arising from its interactions with other nucleons inside the target, results in velocity-dependent terms in the Schrodinger equation that describes nucleon scattering. It has recently been suggested in a number of publications that introducing and fitting velocity-dependent terms improves the quality of the description of nucleon scattering data for various nuclei. The present paper discusses velocity-dependent optical potentials in a context of a three-body… Expand

Perey-effect in continuum-discretized coupled-channel description of (d, p) reactions
The Perey effect in two-body channels of (d, p) reactions has been known for a long time. It arises when the nonlocal two-body deuteron-target and/or proton-target problem is approximated by a localExpand
Theory of deuteron stripping and pick-up reactions for nuclear structure studies
Deuteron stripping and pick-up experiments - (d; p) and (p; d) - have been used for a long time to study the structure of nuclei. Today these experiments are often carried out in inverse kinematicsExpand

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

An approximate three-body theory of deuteron stripping
Abstract A treatment of deuteron stripping is developed in which the three-body effects associated with deuteron break-up in the nuclear field are included explicitly. The essence of the method isExpand
Reduced sensitivity of the (d ,p ) cross sections to the deuteron model beyond the adiabatic approximation
It has recently been reported [Phys. Rev. Lett. 117, 162502 (2016)] that (d, p) cross sections can be very sensitive to the n-p interactions used in the adiabatic treatment of deuteron breakup withExpand

Abstract The object of this paper is to investigate whether it is possible to replace the hard core in current nucleon-nucleon potentials by a non-singular but velocity-dependent potential. This isExpand
