Results of an investigation of the spectra of flare energetic particles aboard the space vehicles Venera 11, 12 and Prognoz 5, 6.

The generation and propagation of energetic solar particles in the proton energy range of 0.1-500 MeV and the electron energy range of 0.03-3.0 MeV were investigated by Venera 11 and 12 and by Prognoz 5 and 6 during December 1976 to September 1979. In this paper, an analysis of the particle spectra in connection with solar-flare parameters is presented. Integrated electron and proton spectra are displayed for a number of flares.
