Statistical models in the polarization radiation theory

The survey is devoted to general results for polarization free-free and free-bound radiative transitions in collisions of charged particles with heavy atoms and ions following from statistical atomic models. The atomic plasma model results for dynamic atomic polarizabilities are presented. Polarization Bremsstrahlung in collisions of fast and moderate energy electrons with Thomas-Fermi atoms is analyzed in details. A new polarization electron-heavy ions recombination channel is considered and compared with known radiative recombination channel. It is shown that recombination channels can be compared or even dominates over standards static radiation channels. Polarization radiation of fast multicharged ions in condensed media is also under consideration.
