Abstract Particle-particle correlations are studied for large- and small-angle separations for the reactions 312 and 680 MeV [sup 40]Ar+[sup nat]Ag. The spectral shapes and angular ansiotropies allow a characterization of the effective temperatures and spin zones of the hot nuclear emission sources. Small-angle correlations are compared to reaction simulations that employ various parametrizations for the emission time scales. We conclude that the initial lifetime scale for [sup 1,2,3]H particle evaporation is of the order of 10[sup [minus]22] s. These times are so short as to suggest a breakdown of the concept of sequential evaporation,'' for which a new ansatz is explored.
