Positronium as a probe of small free volumes in crystals, polymers and porous media
Abstract Positronium (a hydrogen-like bound state of an electron and a positron) is a convenient probe to determine the sizes of subnanometric free volumes (voids) in condensed matter. A review of experimental methods used in positron spectroscopy and examples of their application to the free volume studies are presented.
