Single- and two-particle inclusive cross sections of light particles (p,d,t) were measured for ${}_{}{}^{16}{}_{}{}^{}\mathrm{induced}$ reactions on ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$, ${}_{}{}^{27}{}_{}{}^{}\mathrm{Al}$, and ${}_{}{}^{197}{}_{}{}^{}\mathrm{Au}$ at E/A=25 MeV. The energy and angular distributions indicate that these particles originate from violently interacting subsets of the projectile-target system. For reactions on ${}_{}{}^{197}{}_{}{}^{}\mathrm{Au}$, the two-particle correlations at large relative momenta indicate an ordered motion in the entrance channel reaction plane which is superimposed on the random velocities of the constituents of these subsets. For reactions on ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$, the two-particle correlations appear to be dominated by momentum and energy conservation.
