MUON TRANSFER IN HYDROGEN ISOTOPIC MIXTURES

Direct and inverse muon transfer between atomic orbits of muonic hydro gen isotopes is considered in the WKB approximation. The corresponding cross sections, calculated as functions of collision energy, are diff erent above the thresholds for the inverse transfer and approach commo n limits depending on the principal quantum number and hydrogen isotop es. The comparison of results obtained by integration over impact para meter and by summation over angular momentum is also presented.
