We propose to observe the clusters of galaxies Sersic 159-03 and 2A 0335+096each for 140 ks. The RGS spectra will allow us to spatially resolve thedistribution of the coolest gas in the cluster cores. They also will yield forthe first time accurate measurements of the carbon and nitrogen abundance in acluster. With EPIC two dimensional maps of the temperature and abundance willbe made, allowing us to study the chemical and dynamical history of theseclusters.

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.
