Momentum-space treatment of the Coulomb interaction in three-nucleon reactions with two protons

The Coulomb interaction between two protons is included in the calculation of proton-deuteron elastic scattering, radiative proton-deuteron capture, and two-body electromagnetic disintegration of

-isobar excitation. Calculations are done using integral equations in momentum space. The screening and renormalization approach is employed for including the Coulomb interaction. Convergence of the procedure is found at moderate screening radii. The reliability of the method is demonstrated. The Coulomb effect on observables is seen at low energies for the entire kinematic regime. In proton-deuteron elastic scattering at higher energies the Coulomb effect is confined to forward scattering angles; the

New calculation schemes for proton-deuteron scattering including the Coulomb interaction

Abstract For an uncoupled partial wave without bound state, the symmetric part σ ( k , k ′) of the half-shell T -matrix can be given arbitrarily. This in turn determines the entire T -matrix. Since σ ( k , k ) is essentially the phase shift, the arbitrary part of T appears as a continuation into two dimensions of the phase shift function, symmetry being the only restriction. This formulation stays closer to experiment than the usual one, in which the arbitrary function is the potential V ( k , k ′). A practical method is given to go from σ to the entire T -matrix.
