Recent Experiments on Near-Threshold Electron-Impact Excitation of Multiply Charged Ions
Some recent measurements of excitation of multiply charged ions by electrons studied in beam-beam experiments are highlighted. The emphasis is on absolute total cross sections measured with the merged electron-ion beams energy-loss (MEIBEL) technique, although some results obtained with the crossed-beams fluorescence method are also presented. The MEIBEL technique allows the investigation of op...
متن کاملCTMC calculations of electron capture and ionization in collisions of multiply charged ions with elliptical Rydberg atoms
We have performed classical trajectory Monte Carlo (CTMC) studies of electron capture and ionization in multiply charged (Q ≤ 8) ion-Rydberg atom collisions at intermediate impact velocities. Impact parallel to the minor and to the major axis, respectively, of the initial Kepler electron ellipse has been investigated. The important role of the initial electron momentum distribution found for si...
متن کاملElectron-Impact Total Ionization Cross Sections of Molecular Ions
The Binary-Encounter-Bethe (BEB) model for electron-impact total ionization cross sections of neutral molecules has been modified for molecular positive ions. The total ionization cross sections for [Formula: see text], [Formula: see text], CD(+), and CO(+) from the modified BEB formula are compared to available experimental data. The theory is in good agreement with experimental data on [Formu...
متن کاملElectron-Impact Total Ionization Cross Sections of Hydrocarbon Ions
The Binary-Encounter-Bethe (BEB) model for electron-impact total ionization cross sections has been applied to [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and H3O(+). The cross sections for the hydrocarbon ions are needed for modeling cool plasmas in fusion devices. No experimental data are available for direct com...
متن کاملElectron-impact ionization of Mg
A pulsed crossed beam technique is used to measure ionization cross-sections of metallic atoms. Relative values of cross-sections of single, double and triple ionization of magnesium have been successfully measured with good accuracy over the 0-700 eV range. Absolute values of cross-sections have been obtained by normalization to a theoretical value at high electron energy. Results are compared...
