Probing Baryon Freeze-out Density at the AGS with Proton Correlations

Abstract

First measurements of the beam energy dependence of the two proton correlation function in central Au+Au collisions are performed by the E895 Collaboration at the BNL AGS. The imaging technique of Brown-Danielewicz is used in order to extract information about the proton source at freeze-out. Measured correlation functions and sources do not exhibit significant changes with beam energy.
