Polarization radiation phenomena in plasmas with heavy ions

A polarization channel for radiative transitions (free-free, free-bound, bo und-bound) of electrons in the fields of heavy ions with complex cores is u nder investigation. The channel is connected with a dynamic polarization of an ion's core which results in radiation of the core and an inelastic tran sition of the electron. This channel is estimated in the frame of a statist ical model of the complex ion. The consideration is based on classical mech anics which is applicable to the effects due to the incident electron accel eration in the held of complex ions. It is shown that a contribution of pol arization radiation may be comparable or exceed the standard radiation cont ribution. Scaling laws for radiation intensities in the fields of Thomas-Fe rmi ions are investigated in details. Numerical results are presented for K II ions in plasmas. A comparison with quantum calculations in the statistic al potential is presented.
