Abstract
The variation of the sound velocity at 200 MHz has been measured down to 50 mK in single crystals of niobium doped with oxygen and hydrogen. An effect of the hydrogen tunnelling states on the sound velocity is reported. Some characteristic parameters of these states are then deducedKeywords
