Monte Carlo simulations of nuclear de-excitation gamma-ray line spectra from solar flares

Abstract Recently, we have demonstrated that the Monte Carlo package FLUKA can be used as an effective tool for simulating nuclear processes which occur in solar flares and it is capable to provide a self-consistent treatment of all typical components γ-ray spectra observed those events. In this work, employed new simulation strategy allows improve statistics resolution energy generated spectra. Using strategy, calculated de-excitation lines produced by flare primary accelerated ions with power-law distributions.
