Two-particle correlations at small relative momenta provide information about the space-time extent and the excitation energy density of the emitting system. Detailed measurements of two-particle correlations were performed for /sup 40/Ar-induced reactions on /sup 197/Au at E/A = 60 MeV. In general, more pronounced correlations are measured for particles of higher outgoing energy. From the relative populations of excited states, a mean emission temperature of Tapprox. =5.5 MeV is extracted. Within the framework of the quantum statistical model, our findings are consistent with an expanding nuclear system which disintegrates at low temperature (Tapprox. =5.5 MeV) and rather low density (rho less than or equal to 0.1rho/sub 0/).
