Rapid HeII->HeI recombination and radiation concerned with this process
E. E. Kholupenko, A. V. Ivanchik, D. A. Varshalovich
Recombination of the primordial helium plasma (HeII->HeI, ) is considered. This process has an effect on the CMBR anisotropy and CMBR spectrum distortion. In…

Two-Photon 2s<->1s Transitions during Recombination of Hydrogen in the Universe
E. E. Kholupenko, A. V. Ivanchik
Based on the standard cosmological model, we calculate the correction to the rate of two-photon 2s<->1s transitions in the hydrogen atom under primordial hydrogen plasma recombinat…

CMBR distortion concerned with recombination of the primordial hydrogen plasma
E. E. Kholupenko, A. V. Ivanchik, D. A. Varshalovich
CMBR distortion concerned with recombination of the primordial plasma is calculated in frequency band from 1 GHz to 100 GHz in the frame of the standard cosmological model for diff…
