| Abstract: | The calculation of the radiative energy loss encountered by a fast charged particle which undergoes multiple scattering is being investigated. A detailed derivation of the Landau-Pomeranchuk-Migdal coherent effect in QED is given, focusing on the specific feature of the Coulomb interaction. An exact derivation is provided in the paper following this one. As a result the radiation intensity per unit length in the coherent regime is shown to be proportional to √ω for a photon energy ω times a logarithmic enhancement which is determined exactly. |
