The degradation of low‐energy electrons in alkali halides is calculated using Gryzinski's cross‐section and the Monte Carlo method. The stopping power, the extrapolated range, and the degradation spectrum are obtained in the energy range of 100 to 15000 eV and compared with the results of other theoretical and experimental studies. The yield of double ionization produced by the Auger process and by the direct process is also obtained, and it is shown that the former increases as the energy of the incident electron increases, and the latter decreases as the energy increases above a certain value which is about three times the direct double ionization energy.
