Thank you very much for your answers! I'll have to read more about the interaction with mobile electrons, but now at least I know what to look for. The Feynman lectures will take some time, because there are four of them, but I think it will be worth it.

anti-hydrogen atoms produced at CERN I found it... It was actually produced in my country :), at the "Centre Européenne pour la Recherche Nucléaire" (CERN) in Geneva. http://info.web.cern.ch/Press/PressReleases/Releases2002/PR09.02Eantihydrogen.html

Sure, everyone knows that the angle of incidence equals the angle of reflexion. My question is rather aimed at the atomic level. What is the interaction between electromagnetic radiation and matter? Why can a layer of metal (a mirror) reflect light? Does the interaction occur at the electron...

I remember some anti-hydrogen atom reports, too. However, it existed only for a fraction of a second.
