INTERACTION DEPENDENCE IN A RELATIVISTIC DWIA DESCRIPTION OF PROTON KNOCKOUT

Analyzing powers acid cross sections have been obtained for the (p,2p) reaction on O-16 and Ca-40 for a variety of incident proton energies and outgoing angle pairs. The calculations are based on a finite-range , relativistic DWIA formalism that includes dynamical recoil effects a nd have been carried out with three different input t-matrices of rela tivistic Love-Franey form. Distortions are incorporated by means of re lativistic, energy-dependent optical potentials. It is found that the dependence of the calculated observables on the choice of input t-matr ix is rather weak.
