Observations of powerful radio waves from neutron star magnetospheres raise the question of how strong waves interact with particles in a strong background magnetic field . This problem is examined by solving the particle motion in the wave. Remarkably, waves with amplitudes pump particle energy via repeating resonance events, quickly reaching the radiation reaction limit. As a result, the wave is scattered with a huge cross section. This fact has implications for models of fast radio bursts and magnetars. Particles accelerated in the wave emit rays, which can trigger an avalanche and, instead of silent escape, the wave will produce x-ray fireworks.

磁化粒子对超强电磁波的散射
对来自中子星磁层的强大无线电波的观测提出了一个问题,即强波如何与强背景磁场中的粒子相互作用. 这个问题是通过求解波中的粒子运动来检验的。值得注意的是,波幅通过重复共振事件泵送粒子能量,迅速达到辐射反应极限。结果,波以巨大的横截面散射。这一事实对快速射电暴和磁星模型有影响。在波中加速的粒子发射射线,它可以触发雪崩,而不是无声逃生,波浪会产生 X 射线烟花。
