摘要：

The delayed hard (up to 25 GeV) photons observed more than an hour following a gamma-ray burst on 1994 February 17 may result from the collisions of relativistic nucleons with a dense cloud, producing pi0. The required cloud density is approximately 2 x 10(11) cm-3. This cloud may be the remains of the disrupted envelope of a neutron star, and ma survive as an excretion disk of approximately 10(14)-10(15) cm radius around the coalescing binary.
