ELECTRONS AND X-RAY-EMISSION OF SOLAR-FLARES

A statistical analysis of solar flare X-rays and interplanetary particle fluxes, measured onboard VENERA-13, 14 Spacecraft, was performed. The correlation of fluences for different manifestations of solar flares is strong, especially for fast electrons and hard and soft X-ray emissions. Frequency dependence on fluence value epsilon-i for practically all kinds of solar flare emission can be described by power law nu (epsilon > epsilon-o) approximately epsilon -0.45 +/- 0.15 which does not change significantly with solar activity. For different H-alpha flare importances the values of epsilon-1 were obtained. It is proposed that appearance of certain energy flare frequency is strongly dependent on some scale factor.
