truncated We propose here a deep XMM-Newton observation (4 x 120 ks) of Ark120-- and a joint 120ks Chandra/HETG observation to measure the narrow FeK linecore -- to establish the origin of the soft excess (Comptonization or blurredreflection), its accretion disk properties and its black hole spin. If the softexcess originates from blurred reflection off an ionized accretion disk, we willbe able to clearly detect and resolve, for the first time unambiguously in aBLS1 AGN, broad soft X-ray lines (e.g., OVII, OVIII and FeL). It will be thefirst very high S/N X-ray observation of a bare AGN.

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.
