We propose to perform an {it XMM-Newton} observation of the very faint neutronstar low mass X-ray binary 1RXS J171824.2-402934 to investigate the presence ofa coherent pulsation in the persistent emission of the source. In case ofdetection this will be the first ever detected persistent source with pulsedemission from an accreting neutron star. In case of non detection theobservation will be a emph{crucial experiment} to select current theories ofpulse formation. We will also perform for the first time an aperiodic timinganalysis to search for quasi periodic oscillations that if detected, will giveus precious information about the physics of the system. A spectral study willbe also be performed improving previous Chandra observations.

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.
