The Bombarding Energy Dependence Of Pi(-) Inteferometry At The Ags

We present a preliminary excitation function of pi(-) intensity inteferometry at AGS energies (2-8 AGeV). The sensitivity of the multidimensional correlation functions to both the geometry and dynamics of the hot pion-emitting system provide a stringent test of transport models of heavy ion collisions. Detailed comparisons are performed with the RQMD transport model, both with and without an explicit nuclear meanfield. These comparisons suggest that the evolution in the reaction dynamics with beam energy is different in the model and the data. A suggested signal of the onset of the transition to quark-gluon plasma in the inteferometry excitation function is not observed.
