Abstract
The femtoscopy correlation radii for collisions at 200 GeV are calculated in the hydrodynamic model and compared to data of the PHENIX Collaboration. For asymmetric systems, such as or -Pb collisions, the correlation radius is estimated and predicted to be nonzero. It appears due to different lifetimes of the parts of the fireball at positive and negative rapidities. Azimuthally sensitive Hanbury Brown-Twiss analysis with respect to the second-order event plane shows a significant angular dependence of the radii. It reflects the strong azimuthal asymmetry of the source geometry and flow for central interactions.
