Abstract
Using perturbed angular correlations, we observed decoration of a well-known -vacancy complex in Ni with diffusing H or D atoms. Both partially decorated and saturated configurations are distinguished from the undecorated complex. The saturated configuration is believed to have one hydrogen atom bound in each cavity of vacancy size. Analysis of hydrogen detrapping above 300 K leads to a binding enthalpy ∼0.6 eV, independent of isotopic mass.
