Gliding reflection of positrons from slanting cut crystal

摘要

The phenomenon of occurrence or absence of reflected positron beam depending on direction of gliding over slanting cut crystal is studied. The method of numerical integration of Schroedinger equation was applied to simulation of processes of coherent scattering of positron beams on near surface layers of single crystal. The method can be proposed as a practical probe of surface structure with a number of structural disturbances and also for calculation of RHEED 6 refs., 5 figs.
