We propose to use INTEGRAL to obtain high quality broadband hard X-ray spectraof two Compton-thin Seyfert 2s with insui??cient hard X-ray coverage to date:our primary object, Mkn 348, and a secondary target, the NELG NGC 526a. Bothtargets are X-ray bright, and have archival, long-term averaged RXTE-PCAspectra, as well as XMM-Newton and Suzaku spectra. Our proposed observationswith INTEGRAL IBIS/ISGRI and JEM-X, combined with the lower energy archivalspectra, will allow us to deconvolve broadband spectral components, constrainCompton rei??ection, and search for high-energy continuum cutoi??s. We alsorequest simultaneous XMM-Newton observations to aid in normalizing thelow-energy spectrum.

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.
