The emission of tμ atoms in a two-layer arrangement consisting of H/T and D2 is investigated with an alternative kinetic model. The slowing down of tμ(1s) atoms in pure deuterium and their falling down into resonance regions force chemical confinement fusion (μCF). By considering the resonance escape probability of tμ(1s) atoms, point kinematic equations are numerically solved to obtain the muon conversion efficiency and also the cycling coefficient. Under the optimal condition we show that the μ-cycling coefficient and the efficiency equal 104.5 ± 2.5 and ∼0.7%, respectively. Our model is compared with previous suggestions. The muon conversion efficiency is estimated for a possible design and compared with recent experimental results for H/T⊕D/T.
