  • Nucleon total reaction and neutron total cross sections as well as differential (including spin) observables from 25 to 300 MeV for stable nuclei from 6Li to 238U have been predicted that are in good agreement with measured data. Those predictions have been made using non-local, energy dependent, and complex optical potentials in coordinate space formed by full folding of effective nucleon-nucleon interactions with realistic nuclear ground state densities. By inverse kinematics the same model prescription describes exotic (radioactive) nuclei scattering from hydrogen as a target and the results reveal the extended (neutron) distributions such nuclei can have.
  • It is shown that the nucleon-nucleus scattering amplitude at high energies can be easily obtained by generalizing the nucleon-nucleon scattering amplitude and that it satisfies a simple relation of factorization. In contrast to the Glauber model, in our approach the nucleon structure of the nucleus is not used and the hadron-nucleus scattering amplitude is not expressed in terms of the hadron-nucleon scattering amplitude. The energy dependence of the total and inelastic cross sections for a number of nuclei is described satisfactorily.
  • A review is presented of nucleon--nucleon elastic scattering at large transverse momentum squared. Differential cross sections and the diffraction peak are plotted. Some models are also considered, particularly the Lorentz contracted geometric model. Finally spin at large P/sup 2//sub perpendicular to/ is discussed. 44 references. (JFP)
  • The application of the realistic nucleon--nucleon interaction for the 104-MeV alpha and lithium-6 scattering on calcium 40 is considered. The predictions of a refined folding model approach are compared with recently measured differential cross sections covering a wide angular range. Applying the microscopic potentials for the elastic differential cross sections, an imaginary part must be added in a phenomenological way. Also a normalization factor for the depth of the real folded potential must be introduced. The values of chi/sup 2//F for the best fit obtained with phenomenological real and imaginary potential based on a squared Woods--Saxon form are listed. 11more » references. (JFP)« less
  • The nucleon-nucleon bremsstrahlung amplitude through order k depends on the NN wave function within the strong interaction volume and on the two-body magnetic dipole moment, both of which are unknown. Meson exchange currents have been included by several authors to account for parts of the magnetic moment. The wave function is of major interest. It is shown that the cross section at E/sub L/ = 200 MeV is very sensitive to unitary transformations of the reid soft core wavefunction within 1.5 fm. Results are also shown at 42 MeV.
