Abstract
Several nucleon-nucleon potentials, Paris, Nijmegen, Argonne, and those derived by quantum inversion, which describe the interaction for are extended in their range of application as optical models. Extensions are made in r space using complex separable potentials definable with a wide range of form factor options including those of boundary condition models. We use the latest phase shift analysis SP00 (FA00, WI00) of Arndt et al. from 300 MeV up to 3 GeV to determine these extensions. The imaginary parts of the optical model interactions account for loss of flux into direct or resonant production processes. The optical potential approach is of particular value as it permits one to visualize fusion, and subsequent fission, of nucleons when We do so by calculating the scattering wave functions to specify the energy and radial dependences of flux losses and of probability distributions. Furthermore, half off the energy shell t matrices are presented as they are readily deduced with this approach. Such t matrices are required for studies of few- and many-body nuclear reactions.
