摘要：

We report the COMPTEL detection of pulsed gamma-emission from PSR B1509-58 up to at least 10 MeV using data collected over more than 6 years. The 0.75-10 MeV lightcurve is broad and reaches its maximum near radio-phase 0.38, slightly beyond the maximum found at hard X-rays/ soft gamma-rays. In the 10-30 MeV energy range a strong source is present in the skymap positionally consistent with the pulsar, but we do not detect significant pulsed emission. However, the lightcurve is consistent with the pulse shape changing from it single broad pulse into a double-peak morphology. Our results significantly constrain pulsar modelling.
