Abstract

The claim that the equivalent width of the optical Fe II emission complexes and the soft X-ray slopes of quasars are related is examined. It is shown that among radio-loud quasars, flat radio spectrum objects have flatter soft X-ray slopes. This places steep radio spectrum quasars intermediate in their X-ray slopes between flat radio spectrum and radio-quiet objects. This information may be combined with the observation that steep radio spectrum quasars have weaker Fe II emission to suggest that no correlation between Fe II emission and X-ray spectral slope is expected. An analysis of 15 objects with homogeneously measured Fe II emission strengths and X-ray spectral slopes confirms this prediction. 13 refs.
