The time-dependence of the population of muonic hydrogen states in
hydrogen-helium mixtures is calculated for principal
quantum number n. The number of muons transferred to helium
nuclei is also determined. The dependence of the population of
the ground state of muonic hydrogen 
on time and
target density and the helium concentration is also considered.
The results are in agreement with recent experimental data. The
comparison of the calculated yield of K lines of X-ray
in pure hydrogen and deuterium with experimental data indicates the
essential role of the Coulomb deexcitation process. Possible Stark mixing is
also analysed.
