The NA35 experiment has collected a high statistics set of momentum analyzed negative hadrons near and forward of mid-rapidity for central collisions of 200 GeV/Nucleon {sup 32}S projectiles incident on S, Ag and Au targets. Using two pion momentum space correlations in order to study the size of the source of particle production, small dependences upon transverse momentum are found for the transverse source dimensions; however for the heaviest system, R{sub {ital long}} decreases by about 40% as transverse momentum is increased over the interval 50{lt}p{sub {ital T}}{lt}600 MeV/c. Preliminary model calculations using a microscopic phase space approach (RQMD) appear to reproduce the observed characteristics of the data. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
