The Crab pulsar (PSR B0531+21) has been observed with the EPIC-pn camera on board the ESA XMM-Newton satellite. The high time resolution of the EPIC camera (7 μs) in its special Burst mode in combination with the huge effective area and the high quantum efficiency of the pn-CCD allows phase resolved spectroscopy of good quality over the energy range 0.6–8.5 keV. We performed phase resolved spectroscopy of the modulated flux of the Crab pulsar and found a significant hardening of the photon index in the inter-pulse region. Also the second pulse is harder in index by 0.1 than the first pulse.
