EXTRACTING NUCLEAR TRANSPARENCY FROM P,2P-A AND E,E'P-A CROSS-SECTIONS

We study nuclear-structure effects on the transparency in high-transve rse-momentum (p,2p) and (e,e'p) reactions. We show that in the eikonal -distorted-wave impulse approximation (EDWIA), even when correlations are included, one can get a factorized expression for the transparency which depends only on the average nucleon density p(r) and a correlat ion function. A technique is developed to include correlations in a Gl auber calculation, where we use a Monte Carlo method for integration o ver the nuclear coordinates. We compare calculations of T using the ED WIA formalism, and a continuous density, with a Monte Carlo method bas ed on discrete nucleons.
