  From non-linear theory of electromagnetism, suggested in (physics/9801031),
follows that non-relativistic equation for scalar potential of electron in the
field of nuclei is equivalent to respective Schr\"odinger equation. For mass
and charge densities of electron the expressions from (physics/9811048) are
taken. The energy quantizing demands quantizing of parameters $\nu$ and $q$, as
well as $m$ and $e$.
