We first use perturbative QCD theory to calculate the photon production cross section in nu- cleon - nucleon collisions at a center-of-mass energy of a few tens of GeV, taking into account the intrinsic parton transverse mo- mentum distribution and the next-to-leading-order contributions.

In the past years, the chiral SU(3) quark model has achieved success. In this model, the nonet pseudo-scalar meson exchanges and the nonet scalar meson exchanges are considered in describing the medium-and long-range parts of the interactions, and the one gluon exchange describe the short-range repulsion.

The calculations of nucleus-nucleus potential are carried out in the framework of double folding model with M3Y-Reid and M3Y-Paris effective nucleon-nucleon interactions. The exchange part of the interaction, which is taken to be of finite range and the density dependence of NN interaction, is accounted for in the folding procedure. The results are used as the real part of the optical potential for heavy ion scattering.
