Proton Form Factor Corrections in Hydrogenic Atoms.
Viktor Andreev

We calculated relativistic corrections, which are connected with proton electromagnetic form factors to the energy levels of hydrogen atom with the help of high accuracy technique. To describe a relativistic hydrogen atom we used Poincaré-covariant model of two particle system with a gauge invariant potential.

The high-accuracy technique is based on the application of momentum space and exact calculation of radial equation's kernel for a relativistic fermion-fermion system with electromagnetic interaction. We compute structure-dependent contributions to the hydrogen energy, which involve only one-photon vertex.

Key words: hydrogen atom, Poincaré-covariant model, relativistic Hamiltonian dynamics
