The scattering of nucleons from light nuclei at energies of 142, 210, and 310 MeV is calculated using the multiple-scattering optical potential obtained by retaining all terms which are binary or less in the twonucleon amplitudes. The binary potential includes the impulse-approximation correction as well as the double-scattering correction. Nucleon-nucleus scattering observables are computed, using optical potentials calculated with some of the Yale and Livermore phase-parameter sets and the Fermi and Brueckner-Gammel nuclear-correlation functions. The observables are compared with data in an effort to ascertain the differences caused by changing N-N scattering phase parameters and/or nuclear-correlation functions and to see whether it is feasible to use such changes in attempts to pin down N-N and nuclear parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
