The dynamic polarization potential and dynamical non-locality in nuclear   potentials: Deuteron-nucleus potential
  The consequences for direct reactions of the dynamical non-locality generated by the excitation of the target and projectile are much less studied than the effects of non-locality arising from exchange processes. Here we are concerned with the dynamical non-locality due to projectile excitation in deuteron induced reactions. The consequences of this non-locality can be studied by the comparison of deuteron induced direct reactions calculated with alternative representations of the elastic channel wave functions: (i) the elastic channel wave functions from coupled channel (CC) calculations involving specific reaction processes, and, (ii) elastic channel wave functions calculated from local potentials that exactly reproduce the elastic scattering $S$-matrix from the same CC calculations. In this work we produce the local equivalent deuteron potentials required for the study of direct reactions involving deuterons. These will enable the study of the effects of dynamical non-locality following a method previously employed in an investigation of the effects of non-locality due to target excitation. In this work we consider only excitations due to deuteron breakup, and some new properties of the breakup dynamical polarization potential (DPP) emerge that reveal dynamical non-locality directly. In addition, we evaluate the TELP inversion method and find that it fails to reproduce some features of the DPP due to breakup.
