Relativistic Quantum Chemistry and Spectroscopy of Kaonic Atomic Systems …

kaons (hadrons), the nature of their interaction with nucleons as a result of measurements of the energies of X-ray quanta emitted during transitions of hadrons
between Rydberg states, and hence, as mentioned, allows to determine the masses
and magnetic moments of hadrons. A physically reasonable agreement between
experimental and theoretical data for the kaonic atomic systems can be achieved
only with simultaneous accurate and correct consideration of relativistic, radiation,
and nuclear effects. In order to provide the further improvement of the theoretical
approach and to increase the calculational data accuracy, it is necessary to use more
consistent approach to the strong kaon-nuclear interaction. In this sense, it seems
extremely important more exact information about the electromagnetic interaction
parameters for a kaonic atomic system as it allows to find more true values for the
kaon-nuclear potential parameters. The subsequent more detailed consideration of
more subtle effects such as, for example, the nuclear-polarization corrections etc.
(for example, within the Woods-Saxon model or relativistic mean filed theory), a
spatial distribution of the magnetic moment inside a nucleus (the Bohr–Weisskopf
effect) etc., is extremely useful and interesting too.
