The surface profile is modelled by a random field of two-dimensional isotropy. The treatment is based on the Green function method. The results involve closed form expressions describing the frequency power spectrum of displacement distribution along the surface plane.

Current knowledge of positron-metal boundary interaction is reviewed. The review interlinks such phenomena as positron trapping at surface, escape of positrons from metals, directional action of metal-metal contact on diffusive movement of positrons and interaction of slow positron beam with surfaces. 1990-01-01T00:00:00Z
