Muonic atom cascade processes in the mixture of hydrogen and helium isotopes

The time-dependence of populations of muonic hydrogen states in hydrogen-he lium mixtures, q(n)(He), is calculated for the principal quantum number, n, the target density, phi, and the helium concentration, C-He. The number of muons transferred to the helium nuclei, N-n(tr), is also determined The de pendence of the population of the ground state of muonic hydrogen, q(ls)(He ), on target density and helium concentration is in agreement with recent e xperimental data. The comparison of the calculated yield of K lines of x-ra y in pure hydrogen and deuterium with experimental data indicates nn essent ial role ol: Coulomb deexcitation processes.
