Abstract：
Using the parton distribution functions of Fe given by the extended x-rescaling model,the influence of heavy qarkonium production mechanism to associate J/ψ and γ production in high energy proton-iron collisions is discnssed. The results show that the contribution of the color-octet states should not be ignored. Furthermore,we predict the differential cross section of associate J/ψ and γ. Comparing our theoretical results with the future experiment data,the heavy quarkonium production mechanism can be examined.
