【摘要】 本文认为强磁场中的逆Compton散射可能是γ射线爆的主要辐射机制.其能谱是由源区质子产生的低频光子经强磁场中非热电子的Compton散射形成的.我们利用非相对论情形(B/B_cr≤1,hv_i/m_ec²≤1)下强磁场中的Compton散射微分截面,导出了上述Compton散射的辐射谱公式,由此很好地拟合了典型γ射线爆GB811016的观测能谱.更多还原

【Abstract】 The inverse Compton scattering in strong magnetic field may be the main radiation mechanism for gamma-ray bursts. The energy spectra of the bursts are formed by low frequency photons, which are scattered by non-thermal electrons in strong magnetic field. Using the Compton differential cross section in strong magnetic field for non-relativistic case (B/Bcr<<1, hvi/mec2<<1), we deduce the radiation spectrum formula for the scattering and use it to fit the observational spectrum of GB 811016.更多还原
