Abstract:

Physics in the photon radiation processes, mainly involving electrons, positrons, and $\gamma$-rays, is discussed. Many of these processes actually play a key role in high energy particle radiation in the Universe and the astrophysical examples are described in some details. Readers are assumed to have fundamental knowledges of the electricity and magnetism, and the primary quantum mechanics.
