Muon catalyzed fusion and muon to ³He transfer in solid T₂ studied by X-ray and neutron detection

X-ray and neutron measurements were carried out for muon catalyzed fusion and related phenomena in solid T₂. The X-ray originated from the μ^- to α sticking in muon catalyzed fusion; t + t + μ^- → (μ^- α) + 2n was measured for the first time, yielding K_α X-ray intensity of (μα) atom and the intensity ratio of K_β to K_α. Utilizing the phenomena of ³He accumulation in solid T₂, the X-ray in the μ^- transfer process from (tμ) to ³He was detected, providing a formation rate and radiative decay branching-ratio of (t³Heμ) molecule. From fusion neutron measurements, estimated values were obtained for (ttμ) molecular formation rate as well as sticking probability ω_t in ttμ fusion. A possible new insight in t +t fusion reaction process at a low energy limit is also obtained.
