Muon Dynamics in the Multilayered Target H–T/D2/H2–D2 at Low Temperature

Abstract

Recently, muon catalyzed fusion in the multilayered targets H/D/T at temperature 3 K has been investigated. The latest theoretical and experimental works have confirmed that muon conversion efficiency in such multilayered systems is low. This strongly affects the muon cycling coefficient in the structure H–T/D2/H2–D2. The first layer emits tμ(1s) atoms. They are moderated in the pure deuterium layer. In the third layer, the muonic deuterium atoms rapidly cascade and reach the ground state. The probability that a μp atom reaches the 1s state depends on deuterium concentration. In low concentration of deuterium, the hyperfine transition of dμ(1s) atom is of particular interest. A kinetic model for such processes is given. Our work clearly shows Wolfenstein–Gerstein (W.G.) effect.
