We propose to study the X-ray properties of a complete sample of Seyfert 1galaxies which their optical polarized spectra are similar to those of Seyfert 2galaxies. The optical properties of these objects can be explained if they areobserved at an inclination comparable with the torus opening angle. A systematicanalysis in the X-ray band of these objects would reveal the imprint of both theatmosphere of the torus and the features of the nearly ubiquitous warm absorbersobserved in Seyfert 1 galaxies. The study will produce new insights to ourknowledge on the accretion flow geometry in AGNs.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
