ABSTRACT

Two-pion correlations in roots(NN) = 130 GeV Au+Au collisions at RHIC have been me asured over a broad range of p air transverse momentum k(T) by the PHENIX ex periment at RHIC. The k(T) de pendent transverse radii are similar to results from he avy-ion collision s at roots(NN) = 4.1 , 4.9, and 17.3 GeV, whereas the lon gitud inal radius increases monot onical ly with be am energy. The ratio of the out wards to side wards transverse radii (R-out/R-side) is consistent with unit y and inde pendent of k(T) .
