  • A local representation of the free nucleon-nucleon t matrix has been determined for several projectile bombarding energies between 100 and 800 MeV/nucleon and is presented in tabular form. The form of the interaction has been tailored for use in calculations of elastic and inelastic proton scattering in this energy range. The technique used to derive the interaction is outlined and some of the resulting uncertainties are discussed. A number of the most important properties of the interaction and their roles in the calculation of nucleon-nucleus scattering observables are discussed. A few applications of the interaction are made to a varietymore » of ( p,p') transitions within a single-scattering context.« less
  • A local nucleon-nucleon effective interaction based on current phenomenological nucleon-nucleon scattering amplitudes has been constructed at several bombarding energies between 50 and 1000 MeV/nucleon within a dynamically nonrelativistic framework. The form of the interaction has been chosen for convenience in performing nucleon-nucleus scattering calculations in this energy range and for ease of comparison with one-boson-exchange potential models. Some properties of this interaction are compared with those of an earlier version based on an older set of nucleon-nucleon amplitudes.
  • Nucleon-nucleon (NN) cross sections are evaluated in neutron-rich matter using a scaling model according to density, momentum, and isospin dependent nucleon effective masses. It is found that the in-medium NN cross sections are not only reduced but also have a different isospin dependence compared with the free-space ones. Because of the neutron-proton effective mass splitting the difference between nn and pp scattering cross sections increases with the increasing isospin asymmetry of the medium. Within the transport model IBUU04, the in-medium NN cross sections are found to influence significantly the isospin transport in heavy-ion reactions. With the in-medium NN cross sections,more » a symmetry energy of E{sub sym}({rho}){approx_equal}31.6({rho}/{rho}{sub 0}){sup 0.69} was found most acceptable compared with both the MSU isospin diffusion data and the presently acceptable neutron-skin thickness in {sup 208}Pb. The isospin dependent part K{sub asy}({rho}{sub 0}) of isobaric nuclear incompressibility was further narrowed down to -500{+-}50 MeV. The possibility of determining simultaneously the in-medium NN cross sections and the symmetry energy was also studied. The proton transverse flow, or even better the combined transverse flow of neutrons and protons, can be used as a probe of the in-medium NN cross sections without much hindrance from the uncertainties of the symmetry energy.« less
  • A model for elastic scattering of three-nucleon particles by nuclei is constructed. The total cross-sections for various interactions of /sup 3/H and /sup 3/He nuclei with medium and heavy nuclei are derived.
