Abell 2199 and Abell 3571 show indications of central abundance enhancements dueto SN Ia ejecta contamination. The mechanisms that create the enhancement arenot clear. Some suggested mechanisms to explain this excess of SN Ia material inthe central regions are: ram-pressure stripping, SN Ia suppressed winds andnormal stellar mass loss. The discrimination between metal injection mechanismscan be done by determining the distribution of elemental abundance ratios inclusters. We propose to observe A2199 and A3571 for 20 ksec and 30 ksecrespectively (EPIC MOS) to determine the distribution of individual abundancesand abundance ratios. The results will be used in the discrimination of metalenrichment mechanisms, which will provide fundamental constraints on the energetics of the ICM.

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.
