摘要：
We compute the Coulomb correction to the total and diffractive cross sections for virtual photon scattering off a heavy nucleus at low x. We show that it violates the geometric scaling in a wide range of photon virtualities and is weakly x independent. In heavy nuclei at low Q(2), the Coulomb correction to the total and diffractive cross sections is about 20% and 40%, correspondingly.
