Abstract

Two-pion correlations in $\sqrt{s_{NN}} = 130 GeV$ $Au + Au$ collisions at RHIC have been measured over a broad range of pair transverse momentum $k_{T}$ by the PHENIX experiment at RHIC. The $k_{T}$ dependent transverse radii are similar to results from heavy-ion collisions at $\sqrt{s_{NN}} = 4.1$ , 4.9, and 17.3 GeV, whereas the longitudinal radius increases monotonically with beam energy. The ratio of the outwards to sidewards transverse radii $(R_{out} {/ R}_{side})$ is consistent with unity and independent of $k_{T}$ .
