摘要
将中子星近似看做带有偶极磁场的倾斜转子,本文从经典辐射理论出发,用计算机数值计算方法计算了从星近极区表面飞出的原电子的γ射线辐射角分布。结果表明,影响辐射角分布特性的主要因素是磁力线曲率和电子能量耗散。偶极磁场的强烈畸变将在一定程度上导致辐射的方向弥散.
On the basis of the classical theory of radiation and numerical compu-ting technique, this article makes an investigation on the angular distribu-tion of the gamma-ray radiation emmited by relativistic primary particles flying from the magnetic polar caps of a neutron star with an inclination of x≠0 between its rotating axis and magnetic axis. It is indicated that the major factors which intensely influence the orientation characteristics of the gamma-ray radiation are the curvature of the magnetic line and the energy dissipation of the primary particles. The considerable distortion of the mag-netic line will lead to a certain amount of the directivity dispersion of the radiation.
