A new mechanism for electron transfer in fast ion-atomic collisions

Abstract

We discuss a new mechanism for the electron capture in fast ion-atom collisions. Similarly like in the radiative capture, where the electron transfer occurs due to photon emission, within the mechanism under consideration the electron capture takes place due to the emission of an additional electron. This first order capture process leads to the so called transfer-ionization and has a number of interesting features, in particular, in the target frame it results in the electron emission mainly into the backward semi-sphere.
