  The PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) has
measured J/psi production for rapidities 2.2 < y < 2.2 in Au+Au collisions at
sqrt(s_NN) = 200 GeV. The J/psi invariant yield and nuclear modification factor
R_AA as a function of centrality, transverse momentum and rapidity are
reported. A suppression of J/psi relative to binary collision scaling of
proton-proton reaction yields is observed. Models which describe the lower
energy J/Psi data at the Super Proton Synchrotron (SPS) invoking only J/psi
destruction based on the local medium density would predict a significantly
larger suppression at RHIC and more suppression at mid rapidity than at forward
rapidity. Both trends are contradicted by our data.
