Abstract
A previous derivation of an integral equation, which gives the complete off-energy-shell t matrix for two-body scattering via local potentials with singular core interactions, is generalized to include the effects of tensor and Coulomb forces. The core interaction is described by the boundary-condition model (specified energy-independent logarithmic derivative of the radial wave function at the core radius). The formalism is now being applied to the calculation of trinucleon bound-state and scattering parameters using the Faddeev formalism and realistic nucleon-nucleon forces.
