Simultaneous Generation of Transition Radiation and Bremsstrahlung from a Thin Foil. I

The usual procedure of reducing transition-radiation data by simply subtracting bremsstrahlung yield from the total yield ignores the coherent interference effect between transition radiation and bremsstrahlung. Assuming single scattering, we have analyzed the simultaneous generation of transition radiation and bremsstrahlung of a charged particle normally incident on a thin slab. The results obtained here not only should be useful for reducing experimental data on transition radiation, but also should provide a new independent means to deduce the mean-square angle for single scattering.
