Abstract

The importance of studies with synchrotron radiation for providing dipole oscillator strength distributions in the spectral region between 10 and 100 eV is discussed. Dipole oscillator strengths compiled from photo-absorption and high energy electron inelastic scattering experiments are compared with recent synchrotron measurements for gaseous C₂H₂OH and i-C₄H₈ in the v-u.v. region. The compiled dipole oscillator strength distributions for these gaseous media and for water vapor are used to calculate the inelastic mean free path, mean excitation potential and the range distribution of low-energy electrons. The density normalized ranges are found to decrease in the order H₂O > C₂H₅OH > i-C₄H₈. The actual range of a 1 keV elcetron in H₂O is about 3 or 4 times that in C₂H₅OH and i-C₄H₈, respectively. This difference can have a pronounced effect on track structure.
