The high flux of equivalent photons present in relativistic heavy ion collisions of two chargesZ1 andZ2 gives rise to the collision of two equivalent photons. The cross-sections for various processes are directly related to the correspondingγ- γ cross-sections. As compared toγ- γ physics being studied at e+ e colliders, we find that high energy states will not be so easily accessible at the existing facilities, however, the enhancement factor (Z1Z2)2 in the expression for the cross section will provide very large photon fluxes for lower energies.
