Features of interpretation of pulsed radiation-induced conductivity of polymers at low temperature

The pulsed radiation-induced conductivity of polyethylene and polypropylene was studied at low (about 100 K) temperatures under the influence of electron pulses with an energy of 50 keV and a duration of 1 ms. To explain the results obtained, the Rose-Fowler-Vaisberg model was used. It is shown that when using it, it is necessary to take into account the difference in the shifts of carriers in a unit electric field before the first trapрing and those moving by recapture along traps appearing in the theoretical Rose–Fowler–Vaisberg model. Both of these parameters were calculated based on the results of experimental results.
