Coulomb corrections in quasi-elastic scattering: tests of the effective-momentum approximation
J. A. Tjon, S. J. Wallace
Coulomb corrections for quasi-elastic scattering of electrons by nuclei are calculated using eikonal distorted waves. Corrections to the lowest-order eikonal approximation are incl…
Eikonal analysis of Coulomb distortion in quasi-elastic electron scattering
J. A. Tjon, S. J. Wallace
An eikonal expansion is used to provide systematic corrections to the eikonal approximation through order , where is the wave number. Electron wave functions are obtaine…
Electron-deuteron scattering in the equal-time formalism: beyond the impulse approximation
D. R. Phillips, S. J. Wallace, N. K. Devine
Using a three-dimensional formalism that includes relativistic kinematics, the effects of negative-energy states, approximate boosts of the two-body system, and current conservatio…
Approximate boost of the relativistic two-body problem in instant formalism
S. J. Wallace
Considering two spinless particles, a simple, approximate boost rule is derived that is sufficient to keep the mass invariant and to relate interactions, vertex functions, wave fun…
Transition from hadronic to partonic interactions for a composite spin-1/2 model of a nucleon
J. A. Tjon, S. J. Wallace
A simple model of a composite nucleon is developed in which a fermion and a boson, representing quark and diquark constituents of the nucleon, form a bound state owing to a contact…
Electron-deuteron scattering in a current-conserving description of relativistic bound states: including meson-exchange-current contributions
D. R. Phillips, S. J. Wallace, N. K. Devine
Using a three-dimensional formalism that includes relativistic kinematics, the effects of negative-energy states, approximate boosts of the two-body system, and current conservatio…
Polarization transfer observables for quasielastic proton-nucleus scattering in terms of a complete Lorentz invariant representation of the NN scattering matrix
B. I. S. van der Ventel, G. C. Hillhouse, P. R. De Kock +1
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 Approxi…
A covariant gauge-invariant three-dimensional description of relativistic bound-states
D. R. Phillips, S. J. Wallace
A formalism is presented which allows covariant three-dimensional bound-state equations to be derived systematically from four-dimensional ones without the use of delta-functions.…
