A Correlation Between 4-8 MeV Gamma-Ray-Line Fluence and > 50 Kev X-Ray Fluence in Large Solar Flares
Abstract
For large flares observed by the Solar Maximum Mission (SMM) satellite from 1980-1982, we find a reasonably good correlation between 4-8 MeV gamma-ray-line (GRL) fluences and >50 keV hard X-ray fluences. We find no compelling evidence for a distinct population of large hard X-ray flares that lack commensurate GRL emission. Our results are consistent with the acceleration of the bulk of the approx. 100 keV electrons and approx. 10 MeV protons (i.e., the populations of these species that interact in the solar atmosphere to produce hard X-ray and GRL emissions) by a common process in large flares of both long and short durations.
