Query: Pion Interferometry in AuAu Collisions at sqrt{s_{NN}}=200 GeV   We present preliminary results from a two-pion intensity interferometry
analysis from Au+Au collisions at sqrt{s_{NN}}=200 GeV measured in the STAR
detector at RHIC. The dependence of the apparent pion source on multiplicity
and transverse momentum are discussed and compared with preliminary results
from d+Au and p+p collisions at the same beam energy.
