Outline of Final Research Achievements

In this study, we aim to determine hydrogen tunneling diffusion rate in solid hydrogen using muon relaxation method. For this purpose, in the first step of this study, we try to investigate the interaction between hydrogen and muon through total cross section measurement. The construction of experimental setup for cross section measurement was completed. This system was consisted of scattering gas cell, beam collimator, vacuum pumps and muon detecting counters. Because of accelerator trouble for J-PARC, the beam time was very limited and only feasibility study for cross section measurement was done. The experimental setup for muon relaxation method for solid hydrogen to determine hydrogen tunneling diffusion was also constructed.
