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<y_\ensuremathπ\ensuremathπ<1.3 and transverse momenta 0.1<kT<1.4 GeV/c. The Bertsch-Pratt radii Ro and R_\ensuremathℓ decrease as a function of pair transverse momentum. Ro and Rs are independent of collision energy, while R_\ensuremathℓ shows a slight increase. The source rapidity yYKP scales roughly with the pair rapidity y_\ensuremathπ\ensuremathπ, indicating strong dynamical correlations.
