Nucleon-nucleus scattering is studied with optical potentials derived from solutions of the relativistic Brueckner-Bethe-Goldstone (RBBG) equation using the Bonn interaction. The effective mass, an input parameter in the RBBG calculation, is determin

Nucleon-nucleus scattering is studied with optical potentials derived from solutions of the relativistic Brueckner-Bethe-Goldstone (RBBG) equation using the Bonn interaction. The complex effective mass is determined phenomenologically by a fit to 200

A method is developed for the treatment of the Bethe-Faddeev three body cluster equations in finite nuclei. A matrix method is employed to sum the three hole line graphs in 4 He. For each value of a constant shift C in the intermediate state oscillat

The unique features of low-energy neutron scattering have been used to observe an lJ -dependence of the depth of the real volume optical potential near threshold for 208 Pb + n. At E = 0.5 MeV the s- and d-wave potentials are ∼ 3 MeV deeper than th

The complex equivalent local potential to an imaginary non-local potential obtained in a weak coupling particle vibration model for low energy s-wave neutron elastic scattering from 208Pb is presented. The local potential contains a non-zero real par

A method is presented for the solution of coupled channels for neutron-nucleus scattering assuming a separable form for the coupling potentials. This method, which may be extended to charged particle or heavy ion scattering, should be of use when the

Results are obtained with the classical-equations-of-motion approach which provides a complete microscopic, classical, description including finite-range interaction effects. Nonrelativistic classical-equations-of-motion calculations are made for equ

The neglect of an explicit coupling to antiparticles when solving the relativistic Brueckner-Bethe-Goldstone (RBBG) equation leads to ambiguities of the calculated self-energy. We show that it is possible to obtain a family of weakly momentum-depende

A classical model for heavy-ion collisions, introduced previously, has been extended to include certain effects of the Pauli principle. All nucleons are treated equally. They obey classical dynamics and interact through an ordinary two-body force and

A previously published s-wave scattering function for 1--450 keV neutrons on /sup 60/Ni is averaged for comparison to the scattering from an optical model potential. The scattering length R' is found to be 5.5 +- 0.03 fm at 225 keV. Averaging of the
