  At RHIC the cross section for c-cbar production will be large enough such
that approximately 10 pairs will be produced in each central collision. If a
region of deconfined quarks and gluons is subsequently formed, one would expect
that the mobility of the charm quarks will enable them to form J/Psi through
"off-diagonal" combinations, involving a quark and an antiquark which were
originally produced in separate incoherent interactions. We present model
estimates of this effect, which indicate that the signal for deconfinement at
RHIC may possibly be J/Psi enhancement rather than suppression.
