Query: Identical Particle Interferometry at STAR   We present preliminary results from a two-particle intensity interferometry
analysis of charged pions and neutral kaons emitted from Au+Au collisions at
$\sqrt{s_{NN}}$= 130 and 200 GeV measured in the STAR detector at RHIC. The
dependence of the apparent pion source on beam energy, multiplicity, transverse
momentum and emission angle with respect to the reaction plane are discussed.
