Powers and Doyle proposed the existence of pairs of oxygen atoms in interstitial solid solutions of tantalum, based on internal friction measurements from which an asymmetrical broadening of the observed Snoek peak was derived. The present experiments on high-purity tantalum doped only with oxygen i

Two internal friction peaks have been identified in vanadium. One occurring at 186ยฐC for frequencies of 1 cps is associated with the stress-induced diffusion of oxygen, and the other occurring at 272ยฐC is associated with the diffusion of nitrogen. The corresponding activation energies for these peak
Zener relaxation studies have heen made on three silver solid solutions with a torsion pendulum and an elastic-after-effect apparatus. over the range of temperatures studied an Arrhenius equation describes the results. An Arrhenius plot yields for 32% Cd in Ag tr = lo-16.6se~p (~~$oo/RT); for 44% Au
D= 500 A, the average field was calculated for film thicknesses in the range of 100-5000 A. The voltage across the film corresponding to each thickness was then calculated from the average field. A plot of thickness versus voltage calculated in this manner is compared in Fig. 1 with experimental dat
