On-shell theory for n - d scattering in high partial waves

An approximate amplitude for n - d scattering has been constructed, which depends only on the on-shell two nucleon S13 and S01 amplitudes and their analytic continuation to negative energies as defined by a separable potential model. The theory has been tested by comparison with exact results, and has been found to be a good approximation for partial waves with L2, and for incident neutron lab energies up to about 14 MeV.
