Narrowing of the emission angle in high-intensity Compton scattering
Artikel i vetenskaplig tidskrift, 2016
We consider the emission spectrum of high-energy electrons in an intense laser field. At high intensities (a(0) similar to 200) we find that the QED theory predicts a narrower angular spread of emissions than the classical theory. This is due to the classical theory overestimating the energy loss of the particles, resulting in them becoming more susceptible to reflection in the laser pulse.
