Resumo:

The various approximations of vacuum polarization potential and the higher order corrections up to \alpha^3 are reviewed and quantitatively dicussed. The quadrupol part of the vacuum polarization is established. It leads rather straight forward to a small contribution of vacuum polarization to nuclear polarization. These effects are quantitatively investigated.
