Round table discussion at the PSSD-02 Conference, 2002, Sendai, Japan. Positron Laboratory, University of Halle, Halle(Saale), Germany. Vladimir Bondarenko Vladimir Bondarenko

P ositron annihilation is a result of an encounter of the electron with its antiparticle - Positron. The energy released by the annihilation forms two highly energetic gamma photons, which travel in opposite direction. These gamma rays provide a useful analysis tool which has found many practical applications in physics, chemistry and medicine.

T his site is devoted to the Positron Annihilation as a method of experimental physics used in materials research. Read more...
