RHIC 的 sqrt(s_NN)=130 GeV Au+Au 碰撞中的二π介子相关性已通过 RHIC 的 PHENIX 实验在广泛的对横向动量 k_T 范围内测量。依赖于 k_T 的横向半径与 sqrt(s_NN) = 4.1、4.9 和 17.3 GeV 处的重离子碰撞的结果相似，而纵向半径随束流能量单调增加。向外与向侧的横向半径之比 (R_out/R_side) 与单位一致且与 k_T 无关。
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.
