Positron lifetime measurements show a dominant component corresponding to small vacancy clusters. Doppler Broadening measurements indicate that the size and concentration of defects varies with annealing temperatures up to 400°C. This behaviour is accompanied by a change from the amorphous to a partly crystalline structure, which can be observed by X-ray diffraction studies.}, note = {}, institution = {Universität der Bundeswehr München, Fakultät für Luft- und Raumfahrttechnik, LRT 2 - Institut für angewandte Physik und Messtechnik, Professur: Dollinger, Günther}, }
