Mutiple ionization of rare gases by electron impact

Multiple Ionization of Rare Gases by H+ and He+ Impact

Strong-field double ionization of rare gases.

We have studied the double ionization of helium and other rare gases using an electron-ion coincidence technique. With this scheme, the electron energy spectrum correlated to the creation of a doubly charged ion may be compiled. In all cases, the observed double ionization electron distributions are similar and enhanced at high energies, while the single ionization spectra exhibit distinct diff...

Electron-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...

Electron impact ionization of H_2+

The electron impact ionization cross section of H2 is calculated using a distortedwave approximation. The calculated cross section is compared to the experimental results of Peart and Dolder. The simplicity of the system allows an assessment of the accuracy of the distorted-wave approximation without complications from inaccuracies in the target state, initial continuum state, or final continuu...
