Inhibition and anti-inhibition effects of electron scavengers in hydrocarbons revisited

Positronium formation experiments inn-hexane were performed with C₂H₅Br and CCl₄ as inhibitors and others (decalin, tetralin, benzene, naphthalene, phenanthrene) as anti-inhibitors. Although the results can be interpreted in terms of the anti-recombination and anti-inhibition, it is necessary to consider further some new aspects of intra-spur reactions such as shallow tapping of e⁺ and secondary reactions of Ps. The data thus interpreted correlate excellently with the data of radiation chemistry.
