DOI: 10.1007/s11207-018-1386-2
Abstract: Measurements of solar-flare electron-bremsstrahlung X-rays are affected by Compton scattering in the solar atmosphere of the downward-directed radiation. Here we study how Compton-scattered and energy-degraded radiation from nuclear-deexcitation gamma-ray lines and continua affect the measurements… read more here.
