The high-energy particles emitted by a pulsar prevent the accretion of interstellar matter onto the star. However, during the life of a pulsar the energy output decreases; after a critical time has elapsed, the pulsar mechanism is obviously inhibited, and matter may penetrate through the radius of capture. It is proposed that a possible accumulation of this matter in the region at least as large as the corotational radius is followed by a sudden fall onto the stellar surface. Short bursts of high-energy photons may be expected as a result. A possible explanation of recently observed gamma-ray bursts by this mechanism is discussed.
