Configuration space Faddeev continuum calculations: N-ds-wave scattering lengths with tensor-force interactions

Formulation of the $s$-wave, zero-energy Faddeev-type scattering equations for a model which includes a spin-triplet tensor-force nucleon-nucleon interaction and a Coulomb force between two protons is discussed. Numerical solution of the equations for the Reid-soft-core, Argonne $V_{14}$, and super-soft-core $C$ potential models is obtained using spline techniques. Kohn variational estimates are also presented, and comparison is made with other previously published results. The inclusion of a tensor force does not alter our previous conclusions about the Coulomb force effects on the p-d scattering length, which were based upon $s$-wave nucleon-nucleon potential model studies.
