Аннотация
In the recently suggested non-standard - quasi-molecular mechanism of
recombination, the presence of neighboring proton increases the ionization
energy of hydrogen and decreases the final recombination rate. We note that
both these two effects can lead to the larger value of the present expansion
rate of the universe obtained using CMB data and standard cosmological model,
and thus are able to reduce or resolve the Hubble tension problem.
