Study of the localized vibrations of the hydrogen in solid solution Zr-O by inelastic neutron scattering
Abstract
Dynamics of implanted hydrogen and oxygen atoms in zirconium was investigated at 293 and 80 K and at different concentrations of impurity atoms. Hydrogen vibration energy is solid solution ZrO0.25H0.09 Planck constant approx. = 141 MeV is close to hydrogen vibration energy in sigma phase of zirconium hydride (Planck constant approx. = 138 MeV) changing under adequate conditions. In a specimen with low oxygen content ZrO0.03H0.01 hydrogen vibration energy coincides with maximum position of zirconium hydride optical band. It is suggested that, as in Ti-O-H system, at low oxygen content in Zr-O-H no complete suppression of hydride precipitation occurs. Data on structural analysis of ZrO0.37 and ZrO0.37D0.1 alloys are given.
