Abstract: Nondestructive method for analysis of stoichiometric ratio in metal hydrides has been developed. It is based on analysis of total neutron cross sections for hydride samples measured in the area of slow neutrons with use of neutron spectrometry time of flight method. As on titanium hydride example, it is shown, that measurement and analysis of total neutron cross sections for samples TiHn allow to evaluate the value of ratio metal-hydrogen in hydride (n) with accuracy ∼ 1 %.
Keywords: metal hydrides, slow neutrons, neutron cross sections, stoichiometric ratio.
