Penetration and screening effects in electron bremsstrahlung on ions
Gervids V. I. , Kogan V. I.
A semiclassical theory of electron bremsstrahlung in an arbitrary central field is developed. In the case of radiation from a "hard" multi-electron ion, the theory yields approximate expressions for the total effective emission and for the spectrum. These expressions demonstrate the transition from radiation from a "pointlike" ion to radiation from a bare nucleus.
