We propose a deep EPIC observation of the highly asymmetric young (< 600 yearsold) core-collapse (CC) supernova remnant G350.1--0.3, whose spectrum isdominated by iron-rich ejecta expanding at up to 6,000 km/s away from analmost-stationary thermally emitting neutron star (CCO), and for which a veryhigh nickel abundance has been claimed. We shall quantify emission from Ni andCr, in addition to Fe, to derive constraints on nucleosynthesis in explosiveSi-burning regions. We shall also pursue hints of nonthermal emission, searchfor faint ejecta elsewhere near the CCO, search for the blast wave, and obtain avery deep spectrum of the CCO. G350.1--0.3 may join Cassiopeia A as a majorsource for understanding of CC processes, and we expect this long observation to have archival value.

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.
