N2 - Abstract: The features of the resonant and anomalous structure of the associative ionization (AI) spectra for the case of the dipole-dipole interaction of Rydberg atoms are analyzed using the stochastic approach. The use of this approach makes it possible to quantitatively describe the AI reaction with the formation of a positively charged molecular ion. It is found that the efficiency of asymmetric ionization processes for Auger transitions can exceed that of symmetric ones by orders of magnitude. The important role of this phenomenon for the development of modern applied quantum research and the concept about ionization processes occurring in the ionosphere is discussed. The obtained results can be used to solve a number of fundamental problems of ionospheric plasma physics. This especially concerns the time delay effect of signals of global navigation satellite systems (GNSS), which significantly affects the stability of GNSS operation and remote sensing of the Earth’s surface.
