We discuss the importance of X-ray scattering and Compton reflection in type-2 Seyfert Galaxies , based upon the analysis of ASCA observations of 25 such sources . Consideration of the iron K \alpha , [ O iii ] line and X-ray variability suggest that NGC 1068 , NGC 4945 , NGC 2992 , Mrk 3 , Mrk 463E and Mrk 273 are dominated by reprocessed X-rays . We examine the properties of these sources in more detail . We find that the iron K \alpha complex contains significant contributions from neutral and high-ionization species of iron . Compton reflection , hot gas and starburst emission all appear to make significant contributions to the observed X-ray spectra . Mrk 3 is the only source in this subsample which does not have a significant starburst contamination . The ASCA spectrum below 3 keV is dominated by hot scattering gas with U _ { X } \sim 5 , N _ { H } \sim 4 \times 10 ^ { 23 } { cm } ^ { -2 } . This material is more highly ionized than the zone of material comprising the warm absorber seen in Seyfert 1 galaxies , but may contain a contribution from shock-heated gas associated with the jet . Estimates of the X-ray scattering fraction cover 0.25 – 5 % . The spectrum above 3 keV appears to be dominated by a Compton reflection component although there is evidence that the primary continuum component becomes visible close to \sim 10 keV .
