Positron Annihilation Spectroscopy of Defects in Solid
MRS Proceedings, 1986ABSTRACTThe use of positron annihilation to study vacancy defects and some recent results are reviewed. For metals, theoretical calculations have reached the leyel where they can reliably predict lifetime values of positrons trapped at vacancy defects of various size, geometry and impurity environment. Experimental results are shown on vacancy recovery

Applications of Positron Annihilation Spectroscopy
2009Positron annihilation spectroscopy techniques are well established nuclear techniques with applications which nowadays range from structural investigations of materials to investigations of biological samples and medical imaging. They have extensively been used more than thirty years, but with constant improvements in measuring methods and with new ...

High resolution positron-annihilation spectroscopy with a new positron microprobe
Applied Physics Letters, 1997In cooperation with Zeiss/LEO GmbH, a monoenergetic positron source has been integrated in the electron optical system of a scanning electron microscope by help of a magnetic prism. The electron optics serves both to image the specimen with electrons and to form a positron microbeam that allows local positron-annihilation measurements with a resolution

Development of an Electron-Positron Source for Positron Annihilation Lifetime Spectroscopy
2007Abstract : The extremely strong fields produced by focusing powerful laser pulses into minute volumes of material enable relativistic effects to be used to generate radiation, to accelerate particles, and to produce electrons and positrons from vacuum.
