Two-proton correlation functions, measured at small relative momenta in the ${}_{}{}^3{}_{}{}^{}\mathrm{He}$+Ag reaction at 200 MeV, increase monotonically with the kinetic energy of the detected particles. Very strong correlations are observed for intermediate energy protons. These correlations scale with the weaker correlation functions measured for heavier projectiles, and can be reproduced by the Boltzmann-Uehling-Uhlenbeck equation. Even stronger correlations measured for beam velocity protons, however, may be remnants of the initial state wave functions of the ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ projectiles.
