Query: Beam energy dependence of two-proton correlations at the AGS   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. No significant changes with beam energy were
observed. The imaging technique of Brown-Danielewicz is used in order to
extract information about the space-time content of the proton source at
freeze-out. Extracted source functions show peculiar enhancement at low
relative separation.
