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 Bbg. This problem is examined by solving the particle motion in the wave. Remarkably, waves with amplitudes E0>Bbg 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 γ rays, which can trigger an e± 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bg. 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0>bg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γ射线,它可以触发e±雪崩,而不是无声逃生,波浪会产生 X 射线烟花。
