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
