A Lorentz covariant representation of the NN t -matrix has been obtaained over the energy range from 150 to 500 MeV by solving the integral equation that connects the t -matrix with the K -matrix. The K -matrix is expanded in a complete set of on-she

Analyzing powers and cross sections have been obtained for the (p,2p) reaction on 16O and 40Ca for a variety of incident proton energies and outgoing angle pairs. The calculations are based on a finite-range, relativistic DWIA formalism that includes

Starting from a global optical potential for elastic scattering of protons, we develop potentials for scattering of Λ and Σ hyperons from nuclei. Unlike for the proton, the potentials contain strong Lorentz-tensor components which significantly aff

Analyzing powers have been calculated for the (p, 2p) reaction on 16 O at 504 MeV incident energy using a finite-ranged, relativistic DWIA formalism that includes both dynamical and kinematical recoil effects. A relativistic, Love-Franey parametrizat

Coupled channel calculations for proton-nucleus inelastic scattering are performed using the Dirac formalism. The inelastic scattering of 362, 500, and 800 MeV protons from [sup 40]Ca, [sup 90]Zr, and [sup 208]Pb are considered. Transition potentials

Starting with a general dispersion relation, the three-dimensional relativistic two-body propagator is expressed in terms of relativistic Jacobi coordinates. This procedure can be used with most of the widely used propagators. The propagator, written
