We seek to find impulsive events where H fits these abundance patterns and document the events that do not, suggesting possible reasons for the disparity. For 24 % of the smaller impulsive SEP events, the relative abundance of H fits within one standard deviation of the power-law fit of the abundances of elements 6 <= Z <= 56, relative to coronal abundances. In impulsive events with high intensities, H can be 10 to 100 times its expected value. In a few","authors_text":"Donald V.
