  Title: DO X-RAY SPECTRA OF ALL SEYFERT 2 GALAXIES FIT INTO UNIFIED MODELS ?            


Abstract:
 ASCA results obtained for the Seyfert 2 NGC5252 (Cappi et al. 1996b) have shown that
 a flat (2-10 keV) spectrum associated with a weak iron line cannot be explained by
 enhanced reflection because of the weak iron line. Therefore, they do not fit easily
 into simplest versions of unified models. We propose to observe the bright Seyfert 2
 NGC 7674 and 1040+706 to investigate this problem. Ginga observations indicate that
 both sources have flat spectra (Gamma(2-10 keV)=1.4) and low upper limits on their
 Fe K line. The scientific goals of the proposal are: i) to provide tight constraints
 on the absorption, photon index and Fe K line parameters; ii) to test unified models
 based on reflection from neutral matter, and iii) to look for and model the soft (E < 2 keV) X-ray emission of these Sey2.
