Ternovsky V. Relativistic spectroscopy of heavy atoms with accounting for exchange-correlation and radiation effects

The dissertation presents a new solution to the scientific problem, which is manifested in the development of theoretical foundations of a new precision relativistic spectroscopy of heavy conventional multielectron and exotic hadron (kaon) systems with simultaneous correct accounting of nuclear, radiation, exchange-correlation effects on the basis of formalism of the combined gauge-invariant relativistic many-particle perturbation theory with optimized Dirac-Fock zero approximation and generalized energy approach, a new effective relativistic approach to calculating the parameters of β-decay (allowed transitions) of heavy systems within precision cooperative electron-β-nuclear spectroscopy of atomic systems. New data are obtained for transition energies, oscillator forces, and radiation transition probabilities in the spectrum of thallium Tl, ytterbium Yb, and thulium Tm atoms. For the first time, unique features in autoionization spectroscopy of Yb and Tm, associated with abnormally small widths of autoionization, Rydberg resonances, have been discovered. For the first time, precision data on the energies of levels for higher members of the Rydberg uranium U series have been obtained. In order to obtain new information, detailed calculations of the energy and spectroscopic characteristics of heavy kaonic atoms, in particular, tungsten 184W, lead 207Pb and uranium 238U, have been performed. For the first time, on the basis of a new approach, results have been obtained on the characteristics of a whole series of allowed (super allowed) β-decays. The fundamentally new approaches developed in this work for the first time in theoretical atomic optics and spectroscopy and the original scientific results obtained on their basis with most of the spectroscopic accuracy for the first time together lay the foundations of a new scientific direction in modern theoretical optics and spectroscopy of heavy atomic systems, and for the first time for some Rydberg resonances, the values of their energies and widths have been predicted.
