幂律能谱分布电子的同步-曲率辐射谱

The Synchro-curvature Spectra of Electrons with a Power-law Energy Distribution

根据张家铝等近年提出的同步 曲率辐射新理论 ,在非均匀磁场中电子的辐射已不是同步辐射 ,而是同步 曲率辐射 .论文计算了弯曲磁场中相对论性电子在几种情况下的集体谱 ,发现具有幂律能谱分布的电子 ,其辐射谱并非幂律形式 .因此过去认为是幂律谱的传统的观念似有重新考虑的必要 .

Based on the new synchro curvature radiation mechanism by J.L.Zhang et al., if the magnetic field of a radiation region is not flat and straight, the synchro curvature radiation, not the synchrotron radiation, should be the basis on which a real description is to be achieved. In this paper, the synchro curvature radiation spectrum of electrons is calculated with a power law energy distribution and it is found that in a curved magnetic field, the resulting spectrum of electrons could be clearly distinguished from power law. This means that the previous conclusion is open to question.
