Muon Injection: A muon is introduced into a mixture of hydrogen isotopes such as deuterium and tritium. Muon Replacement: The muon replaces an electron in the hydrogen isotope, forming a muonic atom. Fusion Process: The muonic atom allows the nuclei to get closer, facilitating nuclear fusion and releasing energy. Muon Release: After fusion, the muon is typically freed and can catalyze additional fusion reactions.
