The importance of $(n-n’)$-mixing processes in
$textrm{H}^*(n)+textrm{H}(1s)$ collisions in AGN BLR clouds has been
investigated. Compared to the electron-atom collision processes these processes
must have influence on the populations of hydrogen highly excited atoms in
moderately ionized layers of dense parts of the BLR clouds. From the results it
follows that the investigated $(n-n’)$-mixing processes are of interest for the
research and modelling of such medium. The obtained results could be also
useful for modeling of different stellar atmospheres, as well as for the
investigation of Rydberg states of hydrogen and for the study of their
influence during the cosmological recombination epoch.
