We have measured X-rays and neutrons associated with the muon catalyzed t-t fusion process at the RIKEN-RAL Muon facility. In the X-ray measurement, we observed Kα and Kβ X-rays originating from the muon sticking process in muon catalyzed t-t fusion, and obtained the Kα X-ray yield and the Kβ/Kα intensity ratio. An average recoil energy of the (μ-α) atoms in a solid T2 medium was determined from the observed Doppler broadening width of the Kα X-ray line. The obtained t-t fusion neutron has shown an exponential time spectrum with a single component and a continuous energy spectrum with a maximum energy of 9 MeV. We have determined the t-t fusion neutron yield, the t-t fusion cycling rate and the muon sticking probability from the neutron data. The obtained maximum neutron energy is a very peculiar value from the view point of the reaction Q value (11.33 MeV) with the three-particle decay mode at the exit channel: t + t → α + n + n + Q. The obtained neutron energy distribution was analyzed by a simple model with two neutron energy components; reasonable agreement has been obtained, suggesting a strong (n-α) correlation in the exit channel of the t-t muon catalyzed fusion reaction.
