GT-We propose XMM observations of a sample of Seyfert 1.5--2 galaxies, whichwill enable us to explore many of the current of issues relating to the natureof active galaxies. The orientation implications of unification models will betested by considering whether Seyfert 1.5 -- 2 galaxies generally show a strongCompton reflection component and by detailed modelling of the iron K lineprofile. Similarly the role of scattering in producing the soft X-ray excessesseen in the X-ray spectra of most Seyfert 1.5 - 2 galaxies will be investigated,the physical conditions in the r^ant media determined and the relationshipbetween these scatters and the warm absorbers commonly observed in Seyfert 1.sexplored.

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.
