Metallurgical Studies with Positrons
Abstract
The research performed under these Grants involved the development and application of the positorn annihilation technique to defect studies in metals. The experiments performed during the last three years divide into three categories: (a) the study of the applicability of the simple trapping model to positron annihilation in pure lead as a function of temperature; (b) the study of vacancy-impurity interactions in Pb(Cd) and Pb(Tl) alloys, in order to test the excitonic model of 'fast diffusion' of some impurities in Pb; and (c) the design and testing of multidetector angular correlation setup to perform momentum density measurements in metals with hydrogen, in order to study the role of hydrogen in the electronic structure of pure metals.
