摘要：

We report here the discovery of a 65 ms X-ray pulsar in the supernova remnant G11.2-0.3 with ASCA. The object is known to be a composite supernova remnant that shows both an extended shell component and a compact plerionic component. We have detected a sinusoidal pulsation with an amplitude of similar to 19% in the hard X-ray band (3-10 keV). The object has been proposed to be the historical remnant of the supernova of A.D. 386, which makes it the second candidate for the secure association of a pulsar and a historical supernova after the Crab Nebula and its pulsar.
