Absolute Ionization Cross-Section of tetrafluoromethane by electron impact

Sham Singh Saini And Umesh Bhardwaj

Published By : Laxmi Book Publication

Abstract :

The fragmentation pattern of halo methane (CF4) has been studied by electron impact with reference to Jain-Khare semi-empirical formula in the energy range from threshold to around 350 eV. Absolute cross-sections for electron impact single ionization of CF4 ions leading to the formation of CF3+, CF2+ and C+ are measured, having the corresponding threshold energies are 14.63 eV, 18.97 eV and 31.65 eV respectively.The present results are compared with the previously measured results of Ce Ma et al [11] and K.Stephan et al [12].
