Interactions of Charged Particles and Photons with Matter and Fields
摘要
A charged particle passing through a medium typically interacts with nucleons and electrons of the atoms or molecules in the medium. The interaction probability depends on the interaction cross section, density of the medium and distance the particle travels inside the medium. The interaction cross section depends on particle properties like charge, spin, momentum and mass as well as specific properties of the medium. Most processes are based on the electromagnetic interaction and cause an energy loss of the particle.
