Only electromagnetic interactions are discussed today, non-electromagnetic interactions between the nucleus and the passing particle are neglected. These interactions, the hadronic and weak ones, forms the central topic of subatomic physics…

Three centers using carbon ions are in operation, two in Japan: the HIMAC[7] at Chiba and the HIBMC[8] at Hyogo. In Germany, treatment at the Gesellschaft für Schwerionenforschung (GSI)[9] in Darmstadt, which is primarily a physics laboratory, has been discontinued in 2008, but the new HIT(Heidelberger Ionenstrahl-Therapiezentrum) [10] in Heidelberg, which is a dedicated facility, started in November 2009.
