The muon-catalyzed fusion (μCF) process in tritium was studied by the μCF collaboration on the muon beam of the JINR Phasotron. The measurements were carried out with a liquid tritium target at the temperature 22 K and density approximately 1.25 of the liquid hydrogen density (LHD). Parameters of the μCF cycle were determined: the tt μ muonic molecule formation rate λ tt μ = 2.84(0.32) μs −1 , the tt μ fusion reaction rate λ f = 15.6(2.0) μs −1 , and the probability of muon sticking to helium ω tt = 13.9(1.5)%. The results agree with those obtained earlier by other groups, but better accuracy was achieved due to our unique experimental method.
