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…
