We propose to observe a sample of four Narrow Line Seyfert 1 galaxies withstrong Fe II emission (FeNLS1s) for a total allocation time of 115 ks. The goalof this proposal is to test how common is the spectral hard X-ray (Evirgul7-8 keV)absorption feature in FeNLS1s, recently observed in two objects of this class.This feature appears as a clear signature of dense matter outflowing from thenucleus. If our optically-based criterion (i.e. Fe II4570/Hbeta higher than 1.5)would be efficient in selecting objects with deep sharp X-ray edges, the originof this feature in outflowing clouds would be supported. A frequent occurrenceof this spectral drop will therefore provide clues of an intimate link betweenNLS1s and BAL QSOs phenomena.

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.
