摘要

讨论了自旋极化效应对磁化正电子等离子体同步辐射强度的影响。在由对产生产生的等离子体中,自旋态具有极化依赖的自旋偏置,而在热力学制备自旋态的情况下,它们是均匀分布的。结果表明,极化粒子和非极化粒子的辐射强度有明显差异。

Spin-polarization effects in QED-processes in a pulsar magnetosphere
Influence of spin-polarization effects on the intensity of synchrotron emission from magnetized electron-positron plasma is discussed. In the plasma generated by pair production spin states have polarization-dependent spin bias, whereas in the case of thermodynamical preparation of spin states they are equally populated. It is shown, that radiation intensities from polarized and unpolarized particles are appreciably different.
