Cross Sections for K-Shell Ionization of Atoms by Electron Impact

November 1, 2003
Author(s)
J P. Santos, F Parente, Yong Sik Kim
The relativistic version of the binary-encounter-Bethe (BEB) model is used to calculate cross sections for K-shell ionization of atoms by electron impact. The BEB model requires only two atomic constants, the binding energy and kinetic energy of the K

Electron-Impact Total Ionization Cross-Sections of the Chlorofluoromethanes

January 1, 2003
Author(s)
Karl K. Irikura, M A. Ali, Yong Sik Kim
Electron-impact total ionization cross sections for CCl 3F (Freon 11), CCl 2F 2 (Freon 12), CClF 3 (Freon 13), CHCl 2F (Freon 21), CHClF 2 (Freon 22), and CH 2ClF (Freon 31) are calculated using the Binary-Encounter-Bethe (BEB) theoretical model. The BEB

Ionization of Carbon, Nitrogen, and Oxygen by Electron Impact

July 1, 2002
Author(s)
Yong Sik Kim, J P. Desclaux
Total ionization cross sections of neutral carbon, nitrogen, and oxygen atoms by electron impact are presented. In our theory we have included possibilities that (a) some target atoms used in an experiment were in metastable state close to the ground state

Electron-Impact Total Ionization Cross Sections of Hydrocarbon Ions

February 1, 2002
Author(s)
Karl K. Irikura, Yong Sik Kim, M A. Ali
The Binary-Encounter-Bethe (BEB) model for electron-impact total ionization cross sections has been applied to CH 2 +, CH 3 +, CH 4 +, C 2H 2 +, C 2H 4 +, C 2H 6 +, and H 3O +. The cross sections for the hydrocarbon ions are needed for modeling cool

Ionization of Boron, Aluminum, Gallium and Indium by Electron Impact

November 1, 2001
Author(s)
Yong Sik Kim, Philip M. Stone
Measurements of electron impact of ionization of neutral Al, Ga, and In show large cross sections compared to other elements in the same rows of the periodic table. Semi-empirical and classical calculations of direct ionization cross sections are all

Electron-Impact Total Ionization Cross Sections of SF x (x = 1-5)

July 1, 2000
Author(s)
M A. Ali, Karl Irikura, Yong Sik Kim
Total cross sections for electron impact ionization are necessary quantities for numerical modeling of plasma chemistry and for quantitative mass-spectrometric gas analysis. Theoretical cross sections for SF, SF 2, SF 3, SF 4, and SF 5 are calculated by
