A phenomenological Lorentz covariant representation of the NN t-matrix has been obtained
with parameters that are explicitly energy dependent. The real and imaginary parts of the t …

Using the formalism developed in the paper by Maxwell [Nucl. Phys. A 600 (1996) 509] a
relativistic Love-Franey representation of the NN t-matrix has been obtained over the …

For laboratory kinetic energies between 50 and 200 MeV, we focus on generating an energy-
dependent Lorentz covariant parametrization of the on-shell nucleon-nucleon (NN) …

A Lorentz-invariant representation for NN scattering amplitudes is derived. The general NN
representation assuming parity invariance involves 128 amplitudes for a given isospin, all …

Previous work on the general representation of NN scattering amplitudes in the full Dirac
space of two nucleons is extended to allow a simple realization of the generalized Pauli …

A density-dependent effective interaction is derived from a complete set of Lorentz-invariant
NN amplitudes. Its use in a Schrödinger formalism produces results equivalent to use of the …

A Lorentz invariant form of the NN amplitude is fit with a simple model which includes direct
and exchange first Born terms from a number of ''mesons.''The (complex) couplings and …

Within the framework of the relativistic plane wave impulse approximation (RPWIA),
complete sets of quasielastic (p→, p′) and (p→, n→) spin observables are calculated …

Abstract The relativistic ''no-pair''potential for elastic proton scattering is shown to reduce to a
conventional tρ form using optimal factorization of the optical potential and the impulse …

For the calculation of polarization transfer observables for quasielastic scattering of protons
on nuclei, a formalism in the context of the relativistic plane wave impulse approximation is …
