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

Energy-dependent global Dirac optical model potentials are found by fitting proton elastic scattering data in the energy range 20--1040 MeV for $^{12}\mathrm{C}$, $^{16}\mathrm{O}$, $^{40}\mathrm{Ca}$, $^{90}\mathrm{Zr}$, and $^{208}\mathrm{Pb}$. Thr

In this paper we give the results of a relativistic analysis of elastic and inelastic scattering of 180 MeV antiprotons from {sup 12}C. The calculations are performed within a Dirac coupled-channel framework using a collective model for the transitio

Various relativistic treatments are applied to deuteron-nucleus elastic scattering at intermediate energies. There are various possibilities for spin-one wave equations. Here we have considered three of them, the Kemmer-Duffin-Petiau, Proca, and Wein

Elastic and inelastic observables for the scattering of 500 MeV protons from $^{40}\mathrm{Ca}$ are calculated using either the first-order relativistic or nonrelativistic impulse approximation for the diagonal potentials and a collective model for t

We present global Dirac optical model fits to elastic proton scattering data from heavy nuclear targets at energies between 65 and 1040 MeV. Such optical potentials provide critical input for a wide variety of nuclear reactions. The energy and mass n

It has been shown that there exist transformations that can be used to change the Lorentz transformation character of potentials, which appear in the Dirac equation for elastic scattering. We consider the situation for inelastic scattering described
