Abstract

An experimental evidence is reported on the observation of the Doppler effect in fluorine K-Auger line emitted from a core-ionized SF₆ molecule under an impact of 16keVelectrons. The emitting source of the Auger line is found to acquire a kinetic energy of 4.7±0.3keV. We propose that such large energy is released from the Coulomb repulsion taking place between F⁺ and SF₅⁺ fragment ions under influence of an intense focusing field of the incident electrons. In the presence of the Coulomb field of these ions, the Auger line obtains a polarizationP=76%±7%.
