dc.description.abstract <p>Results of the studies on the electrotransport and chemical diffusion of iron, cobalt and nickel in thorium are described. The transport parameters D and Z* were measured in both (alpha) and (beta)-thorium. The experimental results indicate that these solutes are fast-diffusing species in (alpha)-thorium;The internal friction behavior associated with these solutes in thorium was investigated. Results indicate that there are two relaxation peaks associated with each of these solutes in thorium. Experimental values of the activation energy associated with one of the relaxation peaks are coincident with the values of activation energy for diffusion and suggest that both processes are controlled by the same mechanism. Considerations of other data from this study indicate that this mechanism involves an interstitial defect.</p>
