Abstract: Careful elastic after effect measurements have been performed in Mo after electron irradiation at 5K and after isochronal annealing in search for a reorientation process of <110>-dumbbell self-interstitial-atoms. From previous measurements of the Huang scattering on identically irradiated Mo-samples the expected magnitude of the relaxation strength of this process was known. However, a process of this magnitude does not appear in the relaxation spectra. This means, that a reorientation of the <110>-dumbbell self-interstitial-atom does not occur, neither as a rotation in place nor during the free migration of the <110>-dumbbells. It is proposed to explain this observation by a two dimensional migration of the <110>-dumbbell during which the orientation of the dumbbell axis is conserved. This two dimensional diffusion explains without further assumptions the peculiar behaviour of resistivity recovery observed in earlier studies.
