Electron scavenging in ethanol glasses containing two scavengers

Abstract Ethanol glasses with equimolar concentrations of biphenyl and benzychloride are irradiated with γ-rays at 77 and 4.2 K. The yield of biphenyl anion increases, reaching a maximum and decreases with increasing concentration of the scavengers. The concentration at the maximum depends on the temperature of irradiation. These phenomena were interpreted by the tunneling of the electron from the trapped state to the neutral biphenyl and that from the biphenyl anion to the neutral benzychloride.
