Antiprotonic Hydrogen

  • E. Klempt
Conference paper


Antiprotonic hydrogen is a positronium-like system, but its reduced mass is larger by a factor mp/me and nuclear interactions play a significant role. Recent experiments at CERN have provided data which allow to test our understanding of the nuclear forces and of the atomic effects which govern the cascade of antiproton hydrogen from capture to annihilation.
