CALCULATION OF ENERGY LEVELS FOR HEAVY Li-LIKE IONS WITH ACCOUNT FOR THE RADIATIVE EFFECTS WITHIN THE QED PERTURBATION THEORY: NEW SCHEME FOR LAMB SHIFT
Calculating spectra for a number of the heavy Li-like ions has been carried out on the basis of gauge-invariant quantum electrodynamics (QED) perturbation theory (PT) with an account of relativistic, correlation, nuclear, radiative effects.
