Abstract
Scattering processes for thermal positrons spontaneously emitted from metals with negative work functions are considered. We have calculated the relative rates of emission with and without scattering from surfaces of Al(100), Cr(100), and W(111) as well as the relative trapping rates in the surface state of Al(100). The energy distribution of emitted positrons has also been determined.
