Abstract

The positronium relative contact density in crystalline and amorphous SiO₂ has been determined using the angular correlation of annihilation radiation method. The determined values are 0.31 ± 0.02 and 0.95 ± 0.03, respectively. The difference between these two values reflects the difference in the Ps states.
