Description
Two-particle correlations of identical charged pion pairs from Au+Au collisions at √(sNN)=62.4 and 200 GeV were measured by the PHOBOS experiment at BNL Relativistic Heavy Ion Collider (RHIC). Data for the 15% most central events were analyzed with Bertsch-Pratt and Yano-Koonin-Podgoretskii parametrizations using pairs with rapidities of 0.4<yππ<1.3 and transverse momenta 0.1<kT<1.4 GeV/c. The Bertsch-Pratt radii Ro and Rl decrease as a function of pair transverse momentum. Ro and Rs are independent of collision energy, while Rl shows a slight increase. The source rapidity yYKP scales roughly with the pair rapidity yππ, indicating strong dynamical correlations
