Radiation-Induced Electrical Conductance in the Liquids Argon, Neopentane, and n-Hexane: The Influence of Electron Localization Efficiency on the Free-Ion Yield

Abstract

An extra electron in liquid argon does not form a localized state. The free‐ion yield in liquid argon is ${\mathrm{G(e}}^{-}{)}_{\mathrm{fi}}\text{\hspace{0.17em}≈\hspace{0.17em}5}$ , which indicates that all the ion–electron pairs formed during the x radiolysis of argon become free ions. The difference between the values of $G_{\mathrm{fi}}$ in neopentane (0.9) and n‐hexane (0.13) is due to the smaller efficiency of electron localization in the former than in the latter liquid. The efficiency of electron localization is a function of the geometry of the hydrocarbon molecule.
