Abstract
The rather complicated asymptotic behavior at high energies found in the preceding paper for the Delbr\"uck-scattering matrix element is recast in a simpler form. This is accomplished by introducing a suitable form factor in the transverse plane. This factor, called the impact factor of the photon, also appears in other processes. Moreover, it is verified that the transverse momentum transfer is small in Delbr\"uck scattering.
