We propose XMM-Newton EPIC pn observations of two rapidly rotating neutronstars: PSR J2241-52 and PSR J1810+1744 for 50 and 80 ks, respectively. Throughthese observations, we will establish X-ray spectral properties of these pulsarsfor the first time. This will allow us to put stringent constraints on ther-mode oscillations based upon our precise measurements of their surfaceemission. Such constraints are important to learn about the interior compositionof the sources as well as to guide future gravitational wave searches.

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.
