✦ Synopsis

It is suggested that electrons trapped in irradiated 95% alcohol $ssse~ (+ 5% HZO) do not r-et ~vith the scwenger IIIO[ecules and probably recombine with geminate cations. The scavenging has been interpreted in terms of dry etectrort lX%TCfiOll. There are many indications of the important role of tunnelling in the scavenging of electrons trapped in aqueous glasses [I] . The dependences of the yield of trapped electrons, et, versus time and the scavenger concentration have been predicted and confirmed experimentally. The tunnel mechanism was also proposed for alcohol glasses, based solely on the dependence of GeF on the scavenger concentration [2]. However, the observations of shallow trapped electrons, se;, in ethanol in the presence of biphenyl (a2), N,O, SF, and benzyl chloride (BzCl) [3,4J suggest that ,e; does not react with the scavenger. In order to strengthen the evidence for such suggestion the 95% glasses (+ 5% H,O) of
