摘要Since almost all de-excitation lines from nuclear states excited by flare-accelerated protons and a-particles are emitted promptly after nuclear collisions, the emission photon's energy depends on the velocity of the recoiling nucleus. The energies and widths of gamma-ray lines provide a wealth of information on the directionality and spectra of ions in solar flares. In this paper, we use TALYS code to improve the cross sections of gamma-ray lines production, and calculate the shapes of the 1.634 MeV line from de-excitation of Ne-20 as a function of ion's energy spectra and the heliocentric angle. Taking this line shape as an example, we try to develop a new method of line shape analysis to study the properties of accelerated ions in solar flares.
