Abstract
Reaction processes in muon catalyzed fusion (), or in a deuterium-tritium (D-T) mixture were comprehensively studied by Kamimura, Kino, and Yamashita [Phys. Rev. C 107, 034607 (2023)] by solving the coupled channel (CC) Schrödinger equation under a boundary condition where the muonic molecule was set as the initial state and the outgoing wave was in the channel. We approximate this CC framework and propose a considerably more tractable model using the -matrix method based on the Lippmann-Schwinger equation. Nuclear interactions adopted in the -matrix model are determined by reproducing the cross section of the reaction at low energies. The cross section of the strong-coupling rearrangement reaction is presented in a simple closed form based on our new model. This -matrix model has reproduced most of the calculated results on the above reaction reported by Kamimura et al. (2023) and is applicable to other systems such as .
