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

<table>Restored energy spectra of gamma-rays for different time intervals. Thin lines correspond to 16:31:02–16:31:14, thick lines to 16:31:38–16:31:46, and dashed lines to 16:32:02–16:32:10. Red curves represent the total spectra, black curves electron bremsstrahlung, and blue curves the pion-decay component.</table>
