摘要：

We have assembled data for Seyfert 2 galaxies which have polarized broad lines. In the 2-10keV band, we find heavily absorbed X-ray emission with an absorbing column density of about 10(23) cm(-2). The X-ray luminosity ranges from 10(42) to 10(43) erg s(-1) in the 2 - 10 keV band. We conclude that all of our targets have obscured nuclei. Our results suggest a good correlation between X-ray observation and spectropolarimetry. We also detect soft X-ray emission, and find that the flux ratio to the obscured hard component is about 10%, which is larger than those of Seyfert 2 galaxies for which existence of polarized broad lines have not been reported. We discuss the origin of the soft component. (C) 2000 COSPAR. Published by Elsevier Science Ltd.
