Abstract : Ionization rates generated by atmospheric attenuation of solar protons and alpha particles, with integral exponential rigidity spectrums, are calculated for selected values of particle rigidity and geomagnetic cutoff. Ionization produced by these energetic particles creates polar cap absorption events, which disturb radio and radar communications. The ionization rates are required in order to formulate models for these events. (Author)
