Abstract
Interference patterns due to the coherent electron emission from the atomic centers of a molecule by fast electron impact are experimentally observed in doubly differential cross sections. This behavior is supported by theoretical predictions. Measurements are given for the impact of electrons. The emitted electrons are detected in the energy range from , at observation angles between 30° and 130°. In addition to the interference phenomenon in electron emission following soft collisions, it is shown that interference effects appear for ejected electron energies corresponding to the binary-encounter mechanism.
