X-Ray Line Emission from Scorpius X-1
Abstract
Observations of the Sco X-1 source with a large-area proportional counter suggest the presence of iron-line emission in the spectrum of the source at an energy of 6.6 + 0.2 keV. The counts due to the line are in excess of the continuum and background counts by 6 standard deviations. A comparison of the observed line-to-continuum ratio with calculations yields a value consistent with a normal cosmic abundance of iron in the source.
