Thermalization of low energy electrons in hydrocarbon matrices
The experimental thermalization lengths, lth, for hot electrons e-hot produced by photoionization of solvated electrons in 3-methylpentane glass are discussed. For electron energies ranging from the initial value E0>1 eV down to 0.1–0.2 eV, the electron e-hot is assumed to loss energy mainly due to excitation of intramolecular vibrations with energy losses σE>kBT. It is concluded that this model is in agreement with experimental data on lth. The spatial distribution of subvibrational electrons is obtained.
