A. I. ; McDonald, F. B. ; Meyer, J. P. Abstract The Helios I cosmic-ray observations of the June 3, 1982 and the June 21, 1980 gamma-ray/neutron events are analyzed. The particle intensity vs time plots for the two events are presented and the time of maximum energy spectra, and event-integrated energy spectra are examined. The H-2/H, H-3/H, and He-3/He-4 ratios and the heavy-element compositions of the two events are described. Both gamma-ray/neutron events are shown to be He-3-rich and to have heavy element enhancements that are characteristic of He-3-rich events.
