Investigation of characteristics and realization of nucleus recoil method on fast neutrons for study the hydrogen-material system

The method of studying sorption and diffusion of hydrogen isotopes in different materials was elaborated. The method is based on the measurements of concentration distributions of hydrogen on energy spectra of recoil nuclei formed during interaction of 14 MeV neutrons with hydrogen containing in samples investigated. The experimental apparatus on the basis of neutron generator and registration system using PC computer and corresponding software were created. The movement of the front of α-β phase transition during hydrogen and deuterium diffusion in palladium membrane was observed as well as anomalous temperature behaviour of gas diffusion through membrane at inverse β-α transition.
