Stark mixing of ionic intermediate states in radiative recombination of channeled ions

Stark mixing of intermediate excited ionic states due to combined action of crystal lattice, polarization wake potential and collisions with electrons is considered theoretically. Calculations for radiative recombination of well-channeled Ar and Kr ions under planar channeling in Si crystal show significant influence of the mixing of [n = 2] states on formation of the X-ray spectra and angular correlation between L-REC and Kα1 photons.
