M-C calculations based on the Fröhlich-theory of electron–LO-phonon scattering are used to determine energy losses and attenuation lengths of excited electrons with initial energies E0 < Eg ≈ ≈ 9 eV within the conduction band of SiO2. The attenuation length depending on an electric field F can be described by λa(F) = λ0(E0) exp (bF) increasing in field power direction (F > 0) and diminished in opposite direction (F < 0).
