The dependence of the atomic energy levels on a superstrong magnetic field with account of a finite nucleus radius and mass

Abstract

The influence of the finiteness of the proton radius and mass on the energies of a hydrogen atom and hydrogen-like ions in a superstrong magnetic field is studied. The finiteness of the nucleus size pushes the ground energy level up leading to a nontrivial dependence of the value of critical nucleus charge on the external magnetic field.
