22nd SPARC Topical Workshop

We present a theoretical study of the Compton scattering of photons by K-shell electrons of a target atom. Special attention is paid to the polarization of the scattered photons for the case when the incident photons are themselves linearly polarized. In order to explore this polarization transfer we employ the S-matrix approach and the density matrix theory. Moreover, the S-matrix results are...

Resonant scattering of laser photons off relativistic ion beams can serve as an effective approach for the generation of high-energy photons, as the relativistic Doppler effect leads to a substantial frequency boost of the scattered photons. This idea is expected to be realized by the Gamma Factory project, supported by CERN’s Physics Beyond Colliders programme. The concept involves the...

In exotic atoms, one or more electrons have been replaced by a heavier exotic particle like a muon or antiproton. These systems are ideal candidates to test strong-field QED since the particle orbits much closer to the nucleus due to its higher mass, thus experiencing stronger fields. Many upcoming experiments will use this fact to improve QED tests in high-$Z$ systems. However, to effectively...
