An advanced relativistic energy approach is presented and applied to calculating parameters of electron-nuclear 7-transition spectra of nucleus in the atom. The intensities of the spectral satellites are defined in the relativistic version of the energy approach (S-matrix formalism). and gauge-invariant quantum-electrodynamical perturbation theory with the Dirac-Kohn-Sham density-func... https://cuttingedgecutleryco.shop/product-category/kiritsuke/
