- Аннотация: Appearance of high-energy protons in the solar atmosphere during major solar flares can be identified from the observation of a broad gamma-ray line in the 70-100 MeV range of the flare emission spectrum. From comparison of light curves of the pion-decay emission with those observed in different energy ranges we found the onset and peak times of this gamma-ray emission to be close to the peak times of hard X-ray emission and high-frequency radio emission. This time also corresponds to the peak of the derivative of the soft X-ray emission (SXR) recorded by GOES monitors. The closeness of the peak times for of all these emissions indicates that efficient acceleration of protons up to sub-relativistic energies starts close to the time of the main flare energy release.
