Polarization capture of electrons by ions as a new channel of recombination: Shapes and total recombination rates

A new channel for recombination of free electrons on multicharged ions with complex core is under investigation. The channel is connected with a dynamic polarization of an ion's core by the colliding electron which results in radiation of the core and capture of the electron. This channel (called polarization recombination-PlR) is estimated in the frame of statistical (Thomas-Fermi) model of the complex ion. It is shown that the contribution of PlR to the total recombination rates may be compared or exceed the standard contribution of radiative recombination
