6Abstract
The interaction of hafnium implanted into beryllium single crystals with diffusing oxygen was studied using hyperfine interaction and Rutherford backscattering channeling techniques. It was observed that oxygen is trapped at hafnium in a well defined lattice position. The formation of a 〈0001〉 Hf‐O mixed dumbbell in the tetrahedral interstitial cage of the beryllium lattice is suggested to explain the experimental results
