Abstract	Broadband X-ray spectra of polars and intermediate polars consist ofmultitemperature thermal plasma component,its reflection from whitedwarf & 6.4 keV Fe fluorescence emission line. We propose simultaneousNuSTAR-XMM observation of CD Ind (an asynchronous polar) and Paloma (aspecial IP evolving from IP to polar) for the first time to robustly detectthe reflection hump and resolve the 6.4 keV Fe fluorescence line. Theseobservations will help us in having an idea of the geometry of accretionprocess. Also, we will determine the shock temperature to estimate the massof WD and perform emission line spectroscopy to determine the temperatureand density profile of the post-shock region.

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.
