Abstract：
Using the hypothesis of maximum non-perturbative strong interaction reaction and basing on the character of none unitarity corrections in the amplitude for exchanging the non-perturbative color octet gluer, constituent of Pomeron, in strong-soft interaction processes, we proposed an alternative approach to discuss the electromagnetic decay of η_c into two photons.
