We propose a XMM observational campaign on a sample of three bright atollLMXRBs. Primary scientific goal is the study of the broad Iron K alpha featureto deeply understand its relativistic diskline origin while exploringalternative models based on thermal Comptonization broadening. We request atotal of 150 ksec(50 ks on each source) to be performed for two sources in pntiming mode and for one source in modified pn timing mode for which calibrationand new response matrices have been obtained by our group. Based on thecapability of the RGS, a second science objective of the proposal is the studyof the low energy spectrum to search for broad emission and/or absorptionfeatures (due to ionized O, N, Ne, Fe) similar to the ones observed in other systems.

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.
