A hydrogen — Vacancy complex at substitutional indium in niobium

  • R. -D. Roitzheim

The interaction of a In-monovacancy complex in niobium with hydrogen was studied with the PAC-technique between 24 K and 293 K. At 293 K no significant influence of hydrogen on the monovacancy-induced electric field gradient at the In-site was observed. However at a sample temperature ≤ 135 K a new interaction frequency υQ3=122(1) MHz, η=O, appears in the spectra, which is assumed to be due to the trapping of hydrogen in a well defined location on the axis between probe nucleus and the monovacancy.
