Coulomb plus Nuclear Scattering in Momentum Space for Coupled Angular-Momentum States
arXiv:nucl-th/9402032 · doi:10.1103/PhysRevC.50.3037
Abstract
The Vincent--Phatak procedure for solving the momentum-space Schrodinger equation with combined Coulomb-plus-short-range potentials is extended to angular momentum states coupled by an optical potential---as occurs in spin 1/2 times 1/2 scattering. A generalization of the Blatt--Biedenharn phase shift parameterization is derived and applied to 500 MeV polarized-proton scattering from He3 and C13. The requisite high-precision partial-wave expansions and integrations are described.
