Angular and Abundance Distribution of High-energy Gamma Rays and Neutrons Simulated by GEANT4 Code for Solar Flares

Solar and Stellar Astrophysics 2019-05-22 v1 High Energy Astrophysical Phenomena

Abstract

In the solar flare observed on June 3, 2012, high energy gamma-rays and neutrons were observed. The event includes a remarkable feature of a high neutron/gamma-ratio in the secondary particles. We have examined whether this high n/γ\gamma-ratio can be explained by simulation. As a result of simulations using the GEANT4 program, the high n/γ\gamma-ratio may be reproduced for the case that helium and other heavy ions were dominantly accelerated in the flare.
