dc.descriptionWe present the results of a BeppoSAX observation of PSR J0218+4232 which, for the first time, provides detailed information on the pulsar's temporal and spectral emission properties in the broad band 1-10 keV. We detected X-ray pulses with a pulsed fraction of 73 +/- 12 %. The pulse profile is characterized by two peaks phase separated by 0.47 +/-0.05. The pulsed spectrum is best described by a power-law of photon index 0.61 +/- 0.32 with an unabsorbed (2-10 keV) X-ray flux of 4.1E-13 erg/cm^2/s implying a luminosity of Lx = 1.3E32 Theta (d/5.7 kpc})^2 erg/s and an X-ray efficiency of 4.8E-4 Theta (d/5.7 kpc})^2 where Theta is the solid angle spanned by the emission beam.
