We present results for three charmonia states (psi^prime, chi_c and J/psi) ind+Au collisions at |y|<0.35 and sqrt(s_NN)=200 GeV. We find that themodification of the psi^prime yield relative to that of the J/psi scalesapproximately with charged-particle multiplicity at midrapidity across p+A,d+Au, and A+A results from the Super Proton Synchrotron and the RelativisticHeavy Ion Collider. In large impact-parameter collisions we observe a similarsuppression for the psi^prime and J/psi, while in small impact-parametercollisions the more weakly bound psi^prime is more strongly suppressed. Owingto the short time spent traversing the Au nucleus, the larger psi^primesuppression in central events is not explained by an increase of the nuclearabsorption due to meson formation time effects.
