Query: Pion Interferometry at RHIC: Probing a thermalized Quark-Gluon-Plasma?   We calculate the Gaussian radius parameters of the pion-emitting source in
high energy heavy ion collisions, assuming a first order phase transition from
a thermalized Quark-Gluon-Plasma (QGP) to a gas of hadrons. Such a model leads
to a very long-lived dissipative hadronic rescattering phase which dominates
the properties of the two-pion correlation functions. The radii are found to
depend only weakly on the thermalization time tau_i, the critical temperature
T_c (and thus the latent heat), and the specific entropy of the QGP. The
dissipative hadronic stage enforces large variations of the pion emission times
around the mean. Therefore, the model calculations suggest a rapid increase of
R_out/R_side as a function of K_T if a thermalized QGP were formed.
