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 T-2. The X-ray originated from the mu(-) to alpha sticking in muon catalyzed fusion; t + t + mu(- -->) (mu(-)alpha) + 2n was measured for the first time, yielding K-alpha X-ray intensity of (mu alpha) atom and the intensity ratio of K-beta to K alpha. Utilizing the phenomena of He-3 accumulation in solid T-2, the X-ray in the mu(-) transfer process from (t mu) to He-3 was detected, providing a formation rate and radiative decay branching-ratio of (t(3)He mu) molecule. From fusion neutron measurements, estimated values were obtained for (tt mu) molecular formation rate as well as sticking probability omega(t) in tt mu fusion. A possible new insight in t + t fusion reaction process at a low energy limit is also obtained.
