Abstract

Following the work of Thrane, Petersen and Evans which showed that positron lifetimes for voids in molybdenum were independent of void size, it seemed necessary to re-examine earlier results where larger positron lifetimes had been obtained during the annealing of specimens containing voids. This paper outlines the problem and presents the result of an experiment pointing strongly to impurity effects being responsible for the increased values of τ2.
