Absolute fraction of emitted Ps determined by GEANT4 supported analysis of gamma spectra
The fraction of positronium (Ps) emitted from a surface of a germanium single crystal at high temperature is usually assumed to approach unity at zero positron implantation energy. In the experiment, however, the determination of the absolute Ps fraction is not straight forward since recording a ref...
