众所周知，蟹状星云脉冲星在很宽的电磁波谱范围内发射出具有非常相似特性的窄辐射束，但迄今为止，人们还没有正确理解决定这种辐射束的几何条件。船帆座脉冲星发射的射束在射电和伽马射线光谱区域完全不同，几位作者认为这涉及完全不同的发射区域。本文提出了一个统一的几何方案的发射区的位置，这适用于两个棱镜。无线电辐射位于靠近一个磁极，而伽马射线辐射位于从另一个磁极发散的磁力线上，径向距离为光速半径的0.9。
It is well known that the Crab Pulsar emits narrow beams of radiation with very similar characteristics over a very wide range of the electromagnetic spectrum, but the geometric conditions which determine the beaming have so far not been properly understood. The Vela Pulsar emits beams which are completely different in the radio and the gamma-ray spectral regions, and several authors have suggested that entirely different emission regions are involved. This note presents a unified geometrical scheme for the location of the emission regions, which applies to both pulsars. The radio emission is located close to one magnetic pole, while the gamma-ray emission is located in the field lines diverging from the other magnetic pole, at a radial distance of 0.9 of the velocity-of-light radius.
