Abstract
Trapped electrons (et −) were detected in irradiated PVA films at 77°K. Yield of et − was decreased as evaporating water from the films, indicating that water molecules contribute to construct pre-existing traps in the polymer. The radical produced at 77°K was identified as a precursor of the radical produced at room temperature.Keywords
