Determination of thep−pElastic Scattering Matrix

A phase-shift analysis of $p-p$ scattering data from 10 to 400 MeV is presented. Phase-shift energy-dependent forms having a plausible analytic structure are used, and matrix techniques are employed for the search procedure. An interation process was used to arrive at a self-consistent $p-p$ data set. This analysis is being extended to higher energies and to the $n-p$ system.
