Electron reactions in EGsol;H2O glass. Temperature dependence

摘要

The decay of xhyphen;rayhyphen;inducedetminus;in glycolhyphen;water glass and the reduction ofGlpar;etminus;rpar;by various scavengers have been studied as functions of the temperature. The decay ofetminus;was independent of temperature from 77 to 113 K as expected if the reaction occurs primarily by electron tunneling. The reduction ofGlpar;etminus;rpar;, however, decreased significantly with increasing temperature in the same region, the temperature dependence being larger for less efficient scavengers. The results are qualitatively accounted for by the assumption that a significant fraction of the electrons react prior to formation of stable traps, viz. from shallow, transient traps.
