title = "Positron analysis of defects in metals",
abstract = "New methods are discussed to improve defect analysis. The first method employs mapping of two shape parameters, S and W, of the positron annihilation photopeak. It is demonstrated that the combined use of S and W allows to a better discrimination of defects. The other method is based on background suppression and resolution improvement by the use of two detectors in coincidence. This opens possibilities for characterizing defects by element specific contributions to the momentum distribution of the annihilating e(+)e(-) pair, Examples are given of vacancies in Al-nitride precipitates in iron and manganese oxide precipitates in silver.",
