Two-pion correlation function in An + Au collisions at roots(NN) = 130 GeV have been measured by the STAR (solenoidal trackter at RHIC) detector. The source size extracted by fitting the correlations grows with event multiplicity and decreases with transverse momentum. Anomalously large sizes or emission durations, which have been suggested as signals of quark-gluon plasma formation and rehadronization, are not observed. The Hanbury Brown-Twiss parameters dispplay a weak energy dependence over a broad range in roots(NN).
