| Abstrakt: | The dynamics of oxygen atoms in a Ta-O solid solution is studied. The vibrational energies of interstitial O impurities are determined, and the metal-impurity interaction constants are calculated. The experimental data obtained suggest that an oxygen atom is displaced from the center of the octahedral interstice of the crystal lattice. The oxygen vibrational energy in tantalum is shown to satisfy the relation between the localmode energy and the transition metal-interstitial impurity distance that is common for all M-O systems. |
