Abstract
Double mass-spectrometer measurements are reported of one- and two-electron capture cross sections for Ne2+ Ne, Ar2+ Ar, Kr2+ Kr, Xe2+ Xe, CO2+ N2, Kr4+ Ne in the energy region 400-3600 eV. The symmetrical resonance two-electron processes are compared with the theory of Fetisov and Firsov. The single-electron transitions are believed to occur at pseudo-crossings of potential energy curves and the data are successfully interpreted in terms of transitions at single crossings. Inferences are made of the second ionization potentials of CO and N2, and of the fourth ionization potential of Kr.Keywords
