The aim is to develop effective from the computational point of view of methods to describe the energy and spectral properties of Rydberg atoms in the framework of a quantum defect, the device implemented in the corresponding relativistic multiparticle perturbation theory. In the modern theory there is an urgent need to develop new, high-precision, of course, and ab initio relativistic gaugeinvariant theories of radiative transitions in the spectra of Rydberg atoms, multiply charged ions, but with mandatory use of the unique physical characteristics of these systems. In developing our version of the method of the relativistic model potential at the potential of the core is to realize the potential of the relativistic quantum defect approach Dplyus effective exchange-correlation interaction potential “foreign particle-frame.” Contained in the potential of the model parameter is defined in the framework of QED minimization procedure is gauge-violating contribution to the width of the radiation level in the generation of optimized bases relativistic wave functions (ab initio detection circuit parameter).
