Abstract

Correction factors for systematic shifts of the second-order momentσ2 (linearly related toS−1) of the Doppler broadened annihilation gamma ray lineshape are presented. They allow to compareσ2 values obtained under different experimental conditions. The height of the observed peak, the number of keV/channels used and the number of channels over which the Doppler broadening dsstribution should be considered are bounded by the “a priori” settled relative uncertainty ofgs2.
