Abstract

Using XMM-Newton archive we obtained X-ray spectra for 12 AGN's with strong optical emission lines. Models of our spectra corresponds to Seyfert galaxies. We conclude that for Seyfert galaxies power-law spectral index in 2–12 keV band is less than 1.9 and minimal X-ray flux exceeds 1% of optical flux in u-band.
