Abstract

The pion source as seen through Hanbuary-Brown--Twiss (HBT) correlations at BNL Relativistic Heavy Ion Collider (RHIC) energies is investigated within the UrQMD approach. We find that the calculated transverse momentum, centrality, and system size dependence of the Pratt-HBT radii R_L and R_S are reasonably well in line with experimental data. The predicted R_O values in central heavy ion collisions are larger as compared to experimental data. The corresponding quantity √R_O²\ensuremath-R_S² of the pion emission source is somewhat larger than experimental estimates.
