摘要: The temperature dependence of the positron annihilation parameters in bismuth can be explained as an effect thermal expansion samples. No trapping positrons vacancies, nor any prevacancy is observed. Die Temperaturabhangigkeit der Positronenannihilationsparameter Wismut kann als ein Effekt thermischen Ausdehnung Proben erklart werden. Ein Einflus des Anhaftens von Positronen Leerstellen oder irgendein vorher existierender wird nicht beobachtet.
