Microscopic optical model calculations of nucleon-nucleus scattering over wide mass and energy rates.

摘要

Microscopic optical model potentials are tested against a large body of measurements of elastic differential cross sections and analyzing powers for neutrons (8--40 MeV) and protons (16--60 MeV) scattered from targets ranging from (sup 6)Li to (sup 208)Pb. Reasonably good fits to the data can be found using only three parameters, (lambda)(sub V), (lambda)(sub W) and (lambda)(sub SO), normalizing constants to the real, imaginary and spin orbit potential, respectively. These parameters have a smooth dependence on energy and mass number. 17 refs., 8 figs.
