Abstract
We present the results of a systematic study of the shape of the pion distribution in coordinate space at freeze-out in Au + Au collisions at BNL RHIC using two-pion Hanbury Brown-Twiss (HBT) interferometry Oscillations of the extracted HBT radii versus emission angle indicate sources elongated perpendicular to the reaction plane. The results indicate that the pressure and expansion time of the collision system are not sufficient to completely quench its initial shape.
