Abstract

The change in annihilation line-shape for positrons implanted into a molybdenum surface with a variable-energy positron beam has been analysed in terms of a back-diffusion model. Closer agreement with the experimental data was found if account was taken of epithermal positron and positronium emission using a model of elastic scattering of positrons near the surface.
