On the Onset Time of Several SPE/GLE Events: Indications from High-Energy Gamma-Ray and Neutron Measurements by CORONAS-F

Figure 5

The restored incident gamma-ray spectra of the flare on October 28, 2003 (from [35]). Red curves represent the total spectra, black curves electron bremsstrahlung component, and blue curves the pion-decay gamma-ray spectrum. The thin curves correspond to a power law with varying index and the thick curves correspond to a power law with an exponential cutoff.
