摘要
The absorption cross section σ<sub>abs</sub> of J/ψ produced in relativistic heavy ioncollisions is deduced based on the analysis of the absorption length through which theproduced J/ψ passes in the colliding nuclei.The obtained σ<sub>abs</sub> in A-A collisions is con-siderably higher than that in h-A processes.The reason for this different result is dis-cussed in terms of an analysis of the p<sub>T</sub>-dependence of the produced J/ψ.
