Yields of scavenged electrons have been measured in MCH, 3MP, cumene and <I>tert</I>-butylbenzene at 20°C and −196°C. It has been found that the yield of scavenged electrons is considerably lower at −196°C in the glassy state than at 20°C in the liquid state. The temperature effect on electron scavenging indicates that the difference in the yields of scavenged electrons between the liquid and glassy states is attributed to the variation not of temperature but of the physical conditions of the matrix. We have also investigated the effect of composition in MCH-MTHF mixtures and that of the viscosity of the matrix upon the yield of scavenged electrons at −196°C, which has led us to the assumption that the extent of interactions between thermalized electrons and the matrix would affect the yield of scavenged electrons at −196°C. Since such interactions may be related to the mean free path of electrons, we have calculated the contribution of the electron jump distance to the electron scavenging efficiency. The calculated results appear to explain qualitatively the experimental results.
