The aim of this proposal is to confirm a new idea of anisotropic transfer forresonance photons in an accretion column on magnetic cataclysmic variables,which we have proposed to explain unusually strong Fe-K lines observed from somepolars with ASCA (Terada et al 1999). We have then confirmed the idea vianumerical simulations and via detection of rotational modulation in the Fe-Kline EW with ASCA (Terada et al 2001). However, the observational confirmationof the ..line beaming. effect has so far been confirmed only from a few polars,and with marginal significance. With Newton, we expect to measure the effectfrom a much larger sample, with a much higher significance. The effect, ifestablished, will afford a valuable new diagnostic tool of the plasmas in MCVs.

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.
