GT-XMM observations of newly discovered intermediate polars (IPs) are proposed.Broad band pulse phase resolved spectroscopy will allow to investigate thedifferent emission components observed in the X-ray spectra of IPs. The largecollecting area and high spectral resolution of the EPIC detectors will providehigh quality spectra for a detailed modeling to get insight into the accretionprocess close to the surface of the white dwarf. RXJ1914.4+2456 is of particularinterest. It was proposed as candidate for a soft IP or might be the firstdouble-degenerate polar in which case the 569 s period would indicate theorbital period. We propose a 2nd observation about one year after that ofK. Mason to follow the period history.

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.
