   Evidence from an archival study of ASCA quasars suggests that Fe lines,
   present in the spectra of radio-quiet quasars of moderate luminosity,
   come from partially ionized material. This is in contrast to the cold
   lines seen in Seyferts. More luminous quasars appear not to show iron
   lines. We propose to obtain determinations of iron line energy for
   three more radio quiet quasars in this intermediate luminosity band and
   confirm this result which is important for the diagnosis of accretion
   processes in quasars.
