Inclusive two-particle correlations for ${}_{}{}^{16}{}_{}{}^{}\mathrm{induced}$ reactions on ${}_{}{}^{197}{}_{}{}^{}\mathrm{Au}$ at E/A=94 MeV

Two-particle correlations at small relative momenta were measured for ${}_{}{}^{16}{}_{}{}^{}\mathrm{induced}$ reactions on ${}_{}{}^{197}{}_{}{}^{}\mathrm{Au}$ at E/A=94 MeV, providing information about the space-time localization and excitation energy density of the emitting system. Two-particle correlation functions suggest that emission occurs from a region which is slightly larger than observed for ${}_{}{}^{14}{}_{}{}^{}\mathrm{induced}$ reactions at E/A=35 MeV, but significantly smaller than for ${}_{}{}^{40}{}_{}{}^{}\mathrm{induced}$ reactions at E/A=60 MeV. In contrast, the relative populations of widely separated particle unbound states are found to be surprisingly independent of incident energy and projectile mass.
