An X-Ray Observation in the Atmosphere During the August 7, 1972 Solar Flare
Abstract
An observation carried out with a balloon-borne detector of an additional flux of secondary X-rays (E ≃ 30 keV) at large depths in the atmosphere is described. This excess is attributed to the emission of very hard X-rays during the solar flare of August 7, 1972. The propagation in the atmosphere of the secondary photons resulting from their electromagnetic interactions in the air is computed by utilizing the Monte Carlo method. The computations agree with the observed flux when a very hard solar X-ray spectrum is assumed.
