Abstract

We consider the generation of high-energy neutron and π 0-decay γ-quanta inside magnetic loops on the Sun. Using Monte Carlo simulations we investigate the influence of pitch-angle diffusion upon the characteristics of secondary emission. We consider various cases of diffusion on exterior MHD-turbulence as well as on Alfvén waves generated by accelerated particles through the cyclotron instability. We compare the calculated results to SMM flare observations and show that the observational data on the 3 June, 1982 flare do not contradict the assumption of the impulsive phase acceleration of all the protons, given that the energy spectrum of the accelerated particles is an energy power law.
