Inelasticity effect on neutron scattering intensities of the null-H$$_{2}$$O

Kameda, Yasuo*; Sasaki, Motoya*; Usuki, Takeshi*; Otomo, Toshiya*; Ito, Keiji*; Suzuya, Kentaro; Fukunaga, Toshiharu*

Journal of Neutron Research, 11(3), p.153 - 163, 2003/09

We describe results of time-of-flight (TOF) neutron diffraction of the liquid water null-H$$_{2}$$O in order to investigate the effect of both the scattering angle and the neutron flight path ratio to the observed self-scattering intensities. An empirical inelasticity correction procedure is proposed using the self-scattering intensity observed for the null-H$$_{2}$$O.

Muon catalyzed fusion ($$mu$$CF) is a cyclic reaction where a negatively charged muon itself acts like a catalyst of nuclear fusion between hydrogen isotopes. In this work, we used PHITS code to simulate the behavior of the low-energy muon in a thin layer of the solid hydrogen.

When muons are injected into a deuterium thin film target, muon molecules are formed. The muons released after intramolecular fusion (recycling muons) are important for the development of slow muon beams. In this study, corresponding to an experiment in which recycling muons are transported using a coaxial transport tube, the energy distribution of scattered muons, muons after deceleration, and background radiation due to bremsstrahlung by decay electrons and neutrons are analyzed by numerical simulations.

We are attempting to observe regenerative muons emitted from the surface of a solid hydrogen thin film by muon-catalyzed fusion by irradiating the film with muons that have the same charge as electrons and 207 times the mass of electrons. The main background factors in detecting regenerative muons are scattered muons from the accelerator, which are slowed down to the same level as regenerative muons by the target, and bremsstrahlung generated by the components of the device. The results show that there is little scattering within the solid hydrogen, and that the dominant slowing down process is at the Al foil upstream of the solid hydrogen target. The energy distribution of Bremsstrahlung at the X-ray detection position will be reported.
