Abstract: (APS)

Proton-proton correlations were measured with the "Plastic Ball" detector for two systems, Ca + Ca and Nb + Nb, at 400 MeV/nucleon as a function of proton multiplicity. The source-size radii extracted from these measurements were found to have a cube-root dependence on the proton multiplicity of the event. The deduced freezeout density, the density at which collisions between fragments cease, was found to be about 25% of normal nuclear-matter density.
