It is known from both theory and experiment that muon-catalyzed fusion of light isotopes occurs--see this link http://en.wikipedia.org/wiki/Muon-catalyzed_fusion. But my question--is Tau-Catalyzed Fusion also predicted by theory, let us say between the proton nucleus [P] and deuteron nucleus[NP]? Experiment shows that energy released from muon-catalyzed fusion of [P]+[NP] yields [helium-3] + gamma ray + ~5.5 MeV energy (Alvarez et al. Phy. Rev. 105, 1127 (1956)). Would tau-catalyzed fusion yield same energy result ? Thanks for any help.
