Chemi-Ionization And Chemi-Recombination Processes In Astrophysical Plasmas

摘要

Within the semiclassical approximation chemi-ionization processes during symmetrical-atom-Rydberg-atom collisions were considered, as well as the inverse chemi-recombination processes during the scattering of free electrons by corresponding collisional ion-atom complexes and molecular ions. It was shown that these processes must be taken into account when modelling the low-temperature layers of the solar atmosphere and the atmospheres of some helium-rich stars.
