Abstract The X-ray properties of the supernova remnant G 29.7-0.3 are discussed based on spectral data from the EXOSAT satellite. In the 2 to 10 keV range a featureless power-law spectrum is obtained, the best-fit parameters being: energy spectral index α=-0.77, hydrogen column density on the line of sight NH=2.3.1022 cm−2. The incident X-ray flux from the source is (3.6±0.1) 1011 erg cm−2 s−1 in the 2 to 10 keV range corresponding to an intrinsic luminosity of about 2. 1036 erg s−1 for a distance of 19 kpc. The source was not seen with the imaging instrument thus constraining the hydrogen column density to be NH=(3.3 ±0.3) 1022 cm−2 and the energy spectral index α=1.0±0.15. This new observation is consistent with emission by a synchroton nebula presumably fed by an active pulsar. An upper limit of ∼ 1.5% for the pulsed fraction in the range of periods 32ms to 104 s has been obtained.
