| Abstract: | Based on the geometrical model and absorption mechanism. transverse energy dependence of the yield of charmonium production relative to muon pairs in the mass continuum region in relativistic heavy ion collisions is analysed. Our results fit the data very well. It is shown that nuclear effect is important in explaining the charmonium suppression. |

| Keywords: | yield of charmonium final state absorption transverse energydependence |
