The two-photon radiative collision is examined when the continuum states of one of the atoms participate in the interaction. Authors find that the energy spectrum of the electrons produced consists of energies other than what is expected from direct photoionization. The additional energies are a result of the participation of the discrete levels of the two atoms that have been encountered previously (coherent excitation or deexcitation of superpositions of states of the two different types of the atoms). As a result of this coherent superposition, an intensity modulated C//6 is introduced in the potentials of the final scattering channel. This intensity-induced collisional shift which, when used to cancel out the collisional dephasing between the initial and final scattering states at wide range of internuclear separations, enhances the electron continuum scattering process.
