以膨胀火球模型解释来自γ暴的甚高能γ射线,其中考虑了高能γ射线产生效率,相对论效应以及宇宙背景辐射等因素. 计算表明,大于10GeV的γ射线的喷射可能在火球膨胀开始后约10-5s发生,其到达地面时的通量可达10-4-10-6cm-2.

Very high energy gamma rays from gamma ray bursts are explained by the expanding fireball model. The high energy gamma ray generation efficiency, the relativistic effect, and the absorption in cosmic background radiation are taken into account. It is shown that the ejection of gamma rays with the energies higher than 10GeV may happen at the very beginning of the fireball expansion～10-5s with a fluence up to 10-4-10-6cm-2 arriving at the earth.
