Abstract
The observations of omnidirectional X-ray flux at the top of the atmosphere have been extended upto 200 KeV using a balloon-borne NaI (Tl) scintillator detector at Hyderabad, India. The omnidirectional flux at 60 KeV is found to be 0.0066±0.0014 photons/cm.2 sec. ster. KeV. The X-ray flux in the energy range 50-290 KeV can be adequately represented by the spectrum KE−2.2±0.4. New upper limits to the hard X-ray flux from the quiet sun have also been obtained from the same measurement.
