Primary processes induced in polyethylene film by electron beam irradiation at low and very low temperatures
The pulse radiolysis of low density polyethylene (LPDE), using optical absorption detection and emission spectroscopy, has been investigated in the temperature range 6–150 K, the experiments being complemented by a study of the photoluminescence.
It was found that excitons can be autolocalized at temperatures below 20 K, and this process is strongly dependent on the thermal history of the sample.
