Accelerated electrons above tens of keV and accelerated ions above an MeV are observed to contain 10--50% of the energy released in solar flares. Recent analysis of RHESSI and SMM data has revealed a striking close linear correlation between the 2.223~MeV neutron-capture line and electron bremsstrahlung emission above 300~keV, which suggests that the acceleration of protons above ~30~MeV is linked to the acceleration of electrons above ~300~keV. We investigate the degree to which this correlation holds for electrons of lower energies by comparing the gamma-ray line emission with bremsstrahlung emission down to 50~keV, and we compare RHESSI results with past studies. The work at the University of California, Berkeley, was supported by NASA contract NAS 5-98033.
