Abstract

We have developed an approximate way of dealing with explicit energy-dependence of non-local nucleon optical potentials as used to predict the (d,p)(d,p) cross sections within the adiabatic theory. Within this approximation, the non-local optical potentials have to be evaluated at an energy shifted from half the incident deuteron energy by the npn-p kinetic energy averaged over the range of the npn-p interaction and then treated as an energy-independent non-local potential. Thus the evaluation of the distorting potential in the incident channel is reduced to a problem solved in our previous work in [{\it Phys. Rev. Lett. 110, 112501(2013) and Phys. Rev. C 87, 064610 (2013)}]. We have demonstrated how our new model works for the case of 16^{16}O(d,p)17(d,p)^{17}O, 36^{36}Ar(d,p)37d,p)^{37}Ar and 40^{40}Ca(d,p)41(d,p)^{41}Ca reactions and highlighted the need for a detailed understanding of energy-dependence of non-local potentials. We have also suggested a simple way of correcting the dAd-A effective potentials for non-locality when the underlying energy-dependent non-local nucleon potentials are unknown but energy-dependent local phenomenological nucleon potentials are available.
