Model potentials in liquid water ionization by fast electron impact

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...

Absolute Electron Impact Ionization Cross

Normalized values of cross sections for the production of ions by electron impact on N20 and NO have been obtained by utilizing the relative flow technique. The accurately known values of cross sections for the production of singly charged ions of rare gases from the parent atoms have been used for the normalization. Cross sections for the generation of fragment ions have been measured for the ...

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...

Electron-impact double ionization of a model helium atom

Singleand double-ionization processes in electron scattering from a model helium atom are calculated by a direct solution of the time-dependent Schrödinger equation on a 3D lattice. The Coulomb interaction between the electrons is described by v(r1 ,r2)51/r. and all angular momenta are set to zero. The initial state is a product of the ground state of the model helium atom on a 2D lattice with ...
