The collisional atomic processes of Rydberg alkali atoms in Geo-cosmical plasmas
Lj. M. Ignjatovic, V. A. Sreckovic, M. S. Dimitrijevic
The chemi-ionization (CI) processes in atom-Rydberg-atom collisions are investigated in this contribution. The rate coefficients for CI processes in $\textrm{Li}^{*}(n) + \textrm{N…
The ion-atom absorption processes as one of the factors of the influence on the sunspot opacity
Lj. M. Ignjatovic, A. A. Mihajlov, V. A. Sreckovic +1
As a continuation of the previous investigations of the symmetric and strongly non-symmetric ion-atom absorption processes in the far UV region within the models of the quiet Sun p…
Ion-atom radiative processes in the solar atmosphere: quiet Sun and sunspots
V. A. Sreckovic, A. A. Mihajlov, Lj. M. Ignjatovic +1
In the previous works the significance of the symmetric and non-symmetric ion-atom absorption processes in far UV and EUV regions within a model of the quiet Sun atmosphere, has be…
The influence of -mixing processes in collisions on atoms' populations in weakly ionized helium plasmas
A. A. Mihajlov, Lj. M. Ignjatovic, V. A. Sreckovic +1
The results of semi-classical calculations of rate coefficients of -mixing processes due to collisions of Rydberg atoms with atoms are presented. It…
Excitation and deexcitation processes in atom-Rydberg atom collisions in helium-rich white dwarf atmospheres
V. A. Sreckovic, A. A. Mihajlov, Lj. M. Ignjatovic +1
We aim to show the importance of non-elastic excitation and deexcitation processes in collisions with the principal quantum number $n \ge…
The non-symmetric ion-atom radiative processes in the stellar atmospheres
A. A. Mihajlov, Lj. M. Ignjatovic, V. A. Sreckovic +2
The aim of this research is to show that the processes of absorption charge-exchange and photo-association in collisions together with the processes of photo-dis…
