The authors present an analysis of the formation of charmonium resonances of heavy quark pairs immersed in a deconfined environment for a finite time interval. This is intended to model the J/[psi] suppression due to the possible formation of a color screening quark gluon plasma in heavy ion collisions. In particular, they examine how the x[sub c] and J/[psi] states are affected in a quantum mechanical suppression model. They then investigate how the momentum dependence of the fraction of J/[psi]'s that come from radiative x[sub c] decays or that are directly created can affect the momentum dependence of the resulting J/[psi] suppression. They examine under what circumstances could this suppression momentum dependence be enhanced. This is of interest since previous quantum mechanical analyses have failed to model the strong momentum dependence observed in heavy ion collisions.
