The energy spectrum of accelerated protons in solar flares assuming it is either a Bessel function or a power law, is usually deduced from the fluence ratio of the 2.223 MeV neutron capture line, which is of a delayed nature, to 4-7 MeV nuclear emissions. The spectral index obtained in this way is an integration over time. So far almost no detailed information on how the energetic particle spectrum changes with time is available. In this paper we develop a method to study this question and… CONTINUE READING
