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.
