Trapped electrons in gamma -irradiated light and heavy methanol and ethanol at 77 deg K were photobleached with light of lambda 450-600 nm and the decay was analyzed kinetically. The quantum yield of the bleaching was determined for both alcohols. The yield for the protiated alcohol was found to be 3 to 4 times as large as that for the deuterated alcohol. The remarkable difference in the yield is consistent with the assumption that most of the electrons disappear by a dissociative attachment to alcohol molecules. (auth)
