The effect of ion-irradiation on the state of hydrogen in Nb doped with hydrogen of a concentration of [H]/[M]=0.023 (hydrogen-to-metal-atom ratio) from the gas phase has been investigated at room temperature by the channelling method utilizing a nuclear reaction ^1H(^<11>B,α)αα with a ^<11>B beam of an energy of about 2MeV. It has been demonstrated that, before irradiation, hydrogen is located at a tetrahedral (T) site, while, after irradiation at room temperature with the ^<11>B beam in the off-channelling direction up to a dose of about 1.4×10^<16>/cm^2, hydrogen is displaced from a T site by 0.45-0.55Å towards its nearest neighbour lattice point. It is concluded that this irradiation-induced site change of hydrogen is due to trapping of hydrogen by irradiation-introduced monovacancies. Hydrogen is located at a site displaced from one of the nearest neighbour T sites of a vacancy by 0.45-0.55Å towards that vacancy.
