Optimum twohyphen;body scatteringTmatrix elements on and off the energy shell for various potentials

摘要

Variationally optimizedTmatrices and phase shifts are reported for three potential scattering problems: (1) elastic scattering from a square well with aPstate resonance, (2) elastic scattering from a Morse potential parameterized to fitSstate nucleonndash;nucleon scattering data, and (3) off shell diagonal and nondiagonal scattering from the Reid potential. This last problem, involving a potential with long range attraction and short range repulsion, was selected for study because solving the three body problem within the context of the Faddeev formalism requires for input off shell two bodyTmatrices arising from such a potential.
