Bremsstrahlung spectrum from atomic ions

Theoretical results are presented for the bremsstrahlung spectra from 1-100-keV electrons incident on atomic ions, obtained with numerical relativistic partial-wave calculations based on a description of the process as a single-electron transition in a self-consistent screened central potential. Dependence on incident electron energy $T_1$, fraction of energy radiated $\frac{k}{T_1}$, atomic number $Z$, and degree of ionization $Z_i$, is discussed. The importance of screening is examined and comparisons are made with effective charge predictions.
