Description

The ASACUSA collaboration at CERN has measured some collisional dynamics and chemical-physics properties of antiprotonic helium atoms and ions by laser spectroscopy. These include measurements of the primary populations, collisional lifetimes against antiproton annihilation in the helium nucleus, and Auger decay rates of some antiprotonic states. The experimental results are compared with theoretical calculations.
