Coherent regime of Kapitza-Dirac effect with electrons
Kamila Moriová, Petr Koutenský, Neli LaÅ¡toviÄková Streshkova +5
Electron matter waves coherently diffract when passing through a periodic structure of light formed by two interfering light waves. In this so-called Kapitza-Dirac effect, the elec…
