Measurement of X-ray iron line emission from Cygnus X-3 with the OSO 8 crystal spectrometer.
Abstract
X-ray Fe line emission from Cyg X-3 has been detected at an energy of 6.52 + 0.08 keV with the graphite crystal spectrometer on OSO 8. The measured line energy indicates emission from moderately ionized Fe with a line strength of 0.0097 + 0.0043 photons (cm2 s) -1 corresponding to an equivalent width of 220 + 100 eV.
