Abstract
The solution of the wave equation for electron in a solid can be formally singular on some line. The singularity is smeared out within the distance ~ 10-11cm due to electron "vibrations" caused by its interaction with photons. Because of this localization, the large momentum uncertainty results in the local increase of the electron kinetic energy ~ 1 MeV. This energy enhancement is compensated by the local reduction of zero point energy of photons which can be considered as a potential well producing anomalous electron binding. The electron in this well gets to its bottom emitting photons of the total energy ~ 1 MeV (anomalous emission). These effects can occur in a solid when its surface is bombarded by ions with the energy ~ 1 keV. Photons, produced inside the solid, escape from it and can be detected in addition to the usual Bremsstrahlung of incident ions.
Keywords: Ion irradiation; electron binding.
