Abstract: | Recently, high-quality positron annihilation lifetime measurements showed that four components of lifetime spectra for many liquids could be resolved. The well-known three components (para-Ps (positronium), free positron, and ortho-Ps) and a short-lived ortho-Ps component were obtained in many liquids. This short-lived ortho-Ps is probably caused by secondary reactions of ortho-Ps and other reactants, such as a positive ion, in the positron spur. We report the first results of measurements of the yield of this short-lived ortho-Ps component in the system of hexane and the electron scavengers CCl4, CS2, C6F6, and SF6.Deceased. |
