Abstract
One-electron capture and one-electron loss processes were investigated for metal ions Mg+, Fe+ and Cu+ . The investigation of two-electron capture processes was done for Fe+, C+ , O+ and 02+ ions. The measurements were done in the energy range of 5-30 keV and for gas targets of Ne, Kr and N2, The experimental set-up allowed measurements of the cross section values as low as 10-22 cm2. It was found, for metal ions with the low second ionization potential, that one-electron loss cross sections could be of the same order of magnitude as those for one-electron capture process. The role of two-step processes in the formation of negative ions, influencing the measurements of two-electron capture crossections, was analysed for the gas target thickness range of 10^-3 - 10^-2 torr · cm.
