Samenvatting
Positron Annihilation in Chemistry gives a critical review of the chemistry-oriented positron annihilation research. The only three light particles participating in low energy physics and chemistry are the electron, positron, and positronium. Positronium (Ps) is the most important "anomalous" atom.
This volume gives the only available, critical discussion of the chemistry of the two "strange" light particles, the positron and positronium, while the excess electron has been much discussed. Many unusual phenomena in the reaction kinetics of the positron, positronium, and excess electron, and in radiation chemistry and physics, can be investigated in positron annihilation, which also gives important information on defects in solids.
