Abstract
We have considered secondaries produced by accelerated particles trapped in a coronal magnetic structure as well as by those precipitating down into dense regions of the solar atmosphere. We have calculated time profiles and generation anisotropy for π 0-decay γ-radiation, nuclear γ-ray lines and >10 MeV electron bremsstrahlung in a flare magnetic arch. We have shown that as primary particles move inside a magnetic arch in an inhomogeneous atmosphere the secondary emission turns out to be anisotropical, even if the acceleration process is an isotropical one. On the other hand, the anisotropy of the acceleration process not only influences the directivity of secondary emission but also its intensity decay rate. The exact as well as simple approximate calculation techniques for the angular and temporal characteristics of γ-ray emission are discussed. These techniques may be applied to considering the generation process of another kind of secondary product in flare loops.
