Quasi-Molecular mechanism of cosmological recombination: a scheme of calculation
Tamaz Kereselidze, Irakli Noselidze, Zaal Machavariani
For a quasi-molecular mechanism of cosmological recombination, a scheme of calculation based on a rigorous quantum-mechanical approach is elaborated. The probability of free-bound…
Formation of primordial helium: a rapid and simple scheme of calculation
Tamaz Kereselidze, Zaal Machavariani, Irakli Noselidze
A rapid and relatively simple scheme of calculation is elaborated and applied to cosmological recombination of helium. Employing the nonrelativistic Coulomb Green's function, a wav…
A quasi-molecular mechanism of formation of hydrogen in the early Universe -- a scheme of calculation
Tamaz Kereselidze, Irakli Noselidze
In our recent papers (Kereslidze et all 2019a, 2021) a non-standard quasi-molecular mechanism was suggested and applied to treat the cosmological recombination. It was assumed that…
Influence of a quasi-molecular mechanism of recombination on the formation of hydrogen in the early universe
Tamaz Kereselidze, Irakli Noselidze, John F. Ogilvie
In the framework of a quasi-molecular approach, the formation of hydrogen atom in the pre-recombination period of evolution of the universe is analysed quantitatively. Calculations…
