Abstract：
In this paper we point out that the hadronic production of J/Ψ particle shouldcontain the radiative decay of x_c which is produced in hadron collsions.Our resultsshow that :（1）The difference between the effective coupling constant of J/Ψ and stratonsand the effective coupling constant of Ψ′ and stratons is reasonably decreased.（2）The main results in previous work are preserved.（3）The fractions of J/Ψ′s producedvia the photonic decay of the X_c states are obtained at different √s in the fourprocesses.Finally,we simply compare this model with the production via gluon.
