Large and small angle correlation measurements are reported for 1-1H, 4-4He, and 2-4He pairs from 7.8A and 17A MeV 40Ar+natAg. These measurements are interpreted with the aid of trajectory calculations designed to simulate evaporationlike emission of particles and fragments. The most important physical parameter needed to fit the correlation function peaks is the fractional yield of unstable fragments (8Be or 6Li) compared to independently evaporated particles (4He-4He) or (2H-4He). In this approach, the peaks in the simulated correlation functions contain essentially no information concerning the space-time extent of the emitter source. Nevertheless, these simulations can account for the data very well.
