We have considered details of the lower stages of the muon cascade following formation of highly excited muonic atoms in D,-T, mixtures. We show that when the muon reaches the n = 2 states of the muonic atom, an important modification of the hitherto accepted cascade model takes place. Our new theory predicts that fast (A,+. = 10” s-l) formation of metastable dt p * in tp(2s)-D, collisions and their further decay into tp(ls) + d or dp.(ls) + t together constitute a deexcitation process quickly depleting the n = 2 levels of muonic atoms. The decay into dp(ls) can be seen as a muon transfer from the t ~(2s) to d ~(1s) via an intermediate resonant state of dt CL. This process provides an efficient mechanism for muon return from the tritium to deuterium atom which enhances the population of dp(ls), thereby slowing down the cycling rate of the muon and quenching the fusion yield. This new understanding may help to further optimise physical conditions in order to maximise the fusion yield.
