Abstract
The prediction and discovery of the existence of positron (e+)1-4 and positronium atom (Ps)5,6 led rapidly to the development of a new spectroscopic technique for the study of the structure and composition of matter. The technique quickly expanded across interdisciplinary from physics to chemistry, metallurgy, biochemistry and recently to superconductors. As an early non-destructive and in situ testing tool, positron annihilation spectroscopy (PAS) has been utilized extensively to measure crystal defects.7-9.Keywords
