Electron transfer and ionisation in homonuclear collisions of triply charged Ar and Kr ions

Abstract

Using the crossed-beams technique we have measured absolute total cross sections for electron transfer and total electron loss (transfer+ionisation) in homonuclear collisions of triply charged Ar and Kr ions. Only a slight dependence on the center-of-mass energy is found for the electron transfer cross section in the energy range of about 15–65 keV. The total loss cross sections at 60 keV center-of-mass energy are significantly lower than the only two values obtained by Kim and Janev [Phys. Rev. Lett. 58 (1987) 1837].
