Abstract
Two-pion correlation functions are analyzed at midrapidity for three systems [Formula Presented] Si+Al, Si+Au, and [Formula Presented] Au+Au), seven distinct centrality conditions, and different [Formula Presented] bins in the range 0.1–0.5 GeV/c. Source reference frames are determined from fits to the Yano-Koonin source parametrization. Bertsch-Pratt radius parameters are shown to scale linearly with both number of projectile and total participants as obtained from a Glauber model calculation. A finite lifetime parameter that increases linearly with system/centrality is also reported. The [Formula Presented] dependences of the Bertsch-Pratt radii for the central Si+Au and central Au+Au systems differ only by an overall normalization factor given by the measured system/centrality dependence.
