QED model of the radiation escape from the matter
  A simple model based on QED is presented for the estimation of contribution
of the excited level few-photon decays to the radiation escape from the matter
in the epoch of the cosmological hydrogen recombination. It is shown that apart
from the widely studied two-photon decays, some specific 3-photon decays can
contribute on the level of 0.1% accuracy, required by the recent astrophysical
observations.
