Abstract

The paper presents the intensity and spectral nature of the X-ray emission from Sco X-1 in the energy interval 17-106 keV based on the observations made by a balloon borne scintillation telescope system flown on November 15, 1971 from Hyderabad, India. In the 25-53 keV interval, the spectral distribution is observed to correspond to akT value of 5.5 +1.5-1.1}keV assuming the shape to be exponential. Over the complete energy range of observation, a power law function with the value of exponent equal to 3.6± 0.5 seems to yield an adequate fit. Comparing the present data with those obtained elsewhere, the temporal characteristics of the X-ray emission from Sco X-1 are discussed.
