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

Comments on 'Electron Impact Ionization of Methane'

May 1, 2000
Author(s)
Yong Sik Kim, M E. Rudd
It has been claimed by Khare, Sharma and Tomar (1999 J. Phys. B: At. Mol. Opt. Phys. 32, 3147) that the binary-encounter dipole (BED) model and its simpler version, binary-encounter Bethe (BEB) model, for electron impact ionization of atoms and molecules

Electron-Impact Total Ionization Cross Sections of Molecular Ions

March 1, 2000
Author(s)
Yong Sik Kim, Karl Irikura, M A. Ali
The Binary-Encounter-Bethe (BEB) model for electron-impact total ionization cross sections of neutral molecules has been modified for molecular ions. The total ionization cross section for H + 2, N + 2, CD +, and CO+ from the modified BEB formula are

Electron Collision Cross Section Data For Plasma Modeling

October 1, 1999
Author(s)
W M. Huo, Yong Sik Kim
An overview of the current status in electron collision cross section database for plasma modeling is presented. Emphasis is on dissociation, ionization, and dissociative ionization. The effect of the operating conditions on the relative importance of

Theory for Ionization of Molecules by Electrons

March 1, 1999
Author(s)
Yong Sik Kim, M E. Rudd
A simple yet effective theory for the total ionization cross sections of molecules by electron impact is described. The theory, called the Binary Encounter Bethe [BEB] model, combines a modified form of the Mott cross section for low incident energies T

Electron-Impact Total Ionization Cross Sections of CF 4 , C 2 F 6 , and C 3 F 8

February 1, 1999
Author(s)
H Nishimura, W M. Huo, M A. Ali, Yong Sik Kim
Both theoretical and experimental electron-impact total ionization cross sections of CF 4, C 2F 6, and C 3F 8 are presented. The experimental cross sections have been measured as a function of incident electron energy T from threshold to 3 keV. A parallel
