Abstract
It is proposed a new approach to calculating а correction due to the vacuum polarization by nucleus field in the Coulomb systems, including heavy and superheavy finite fermi-systems. New approach is naturally included to а general formalism of QED perturbation theory with using gauge-invariant basises of relativistic bi-spinors in the zeroth order.
