Positron Annihilation in Chemistry [Paperback]

The only critical discussion available on the chemistry of the two strange light particles, the positron and positronium, with much space devoted to the excess electron. Positron annihilation allows the investigation of many unusual phenomena in the reaction kinetics of the positron, positronium, and excess electron, and in radiation chemistry and physics, while also providing important information on defects in solids.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.1.Introduction.- 1.1 Positron Annihilation in Chemistry.- 1.2 History of Chemistry-Oriented PositronAnnihilation Studies.- 1.3 Review of Physics-Oriented Positron Research.- 1.4 The Content and Intention of this Book.- 2 Theory.- 2.1 The Annihilation Probability.- 2.2 Atomic Physics of Positronium (Ps).- 2.3 Application of the Theory.- 3 Experimental Techniques.- 3.1 Positron Lifetime (LT) Technique.- 3.1.1 Elementary Description of a LT Spectrometer.- 3.1.2 Special Problems of LT Measurements.- 3.1.3 General Remarks on the Data Analysis.- 3.1.4 Data Analysis of LT Spectra.- 3.2 Angular Correlation (AC) Measurements.- 3.2.1 Experimental.- 3.2.2 Data Analysis of AC Spectra.- 3.3 Doppler Broadening (DB) Measurements.- 3.4 Miscellaneous Measurements.- 4 Light Particle States in Insulating Matter.- 4lÓw
