On electron trapping in crystalline hydrocarbon matrices

Abstract

The formation of trapped electrons in γ-irradiated polycrystalline hydrocarbon matrices is examined by E.S.R. at 77 and 4 K. Results indicate that no thermalized electrons are trapped in polycrystalline matrices of linear hydrocarbons (from n-hexane to n-hexadecane). They also strongly suggest that the trapped electrons in polycrystalline hydrocarbons so far reported may have been trapped in glassy regions in the matrices used.
