Abstract

Results from a pion interferometric analysis of the system 200 GeV/nucleon 16O + Au, central collisions, are reported. Both a Gaussian source model and a model based on the inside-outside cascade are used to fit to the experimental correlation function, giving transverse and longitudinal shape parameters, a freezeout time parameter, and a chaoticity parameter for the pion emitting source. We find a transverse source size consistent with the projectile radius except for a narrow rapidity window centered about the CM rapidity, where significantly larger transverse and longitudinal sizes and a longer freezeout time are measured suggesting a thermalized source. Calculation of freezeout energy densities and correlation lengths, a fit to a single–event correlation function, and comparisons with other pion interferometry experiments are presented.
