Essay

It is carried out a new, highly exact,ab initio approach to calculation of the spectra, hyperfine structure parameters for heavy atoms and multicharged ions with account of relativistic, correlation, nuclear, radiative effects, based on tghe gauge-invariant QED perturbation theory. It has been carried out calculation of the hyoerfine structure characteristics, energies, constants, nyclear electric quadrupole moments plus deriviatives from energy contributions on nuclear radius for atoms of Cs,Ba,Hg,Ra,Mn,H, H-like ion witn nuclear charge 170. Significant part of highlyexact data is at first obtained and can be used in the whole number of applications, including a theory of nucleus,non-linear optics, laser spectroscopy, astrophysics, physics of plasma etc.
