We propose offset pointings of two intermediate ( M_{500} =1.5 - 3.5 times10^{14} {rm M}_odot ) mass clusters, MKW3s and A2589, to derive metal abundancesup to 0.9 R_{500} and 0.7 R_{500} , respectively, a challenging distance forsystems with these masses. By combining X-ray data with optical data we willderive the iron-yields for these systems and compare them with expected ironyields from supernova rates. Since intermediate mass clusters represent a bridgebetween galaxy groups and massive galaxy clusters, this study will help to solvethe conundrum of the different behavior of galaxy groups, which seem to matchexpected values from supernovae, and massive clusters, which feature adiscrepancy by a factor 3-7 .

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.
