ESR study of trapped electrons produced in alkane glasses at 40K

In gamma irradiated 3-MP, MCH, and 3-MHX glasses, the same et− yields were obtained between 4 and 71°K, indicating that electrons are stabilized in pre-existing traps prior to solvation. The linewidths were reduced on warm-up of the glasses irradiated at 4°K and depended on the annealing time at 71°K, implying that the solvation occurs very slowly around 71°K. A comparative study of power saturation in 3-MP and MCH suggested that the spurs formed at 4°K were spatially expanded compared to those at 71°K. The structural change of trapping sites caused by solvation was clearly reflected on the power saturation characteristics.
