Electron ionization cross sections for the PH3 molecule

The partial single, double differential cross-sections with their total (sum of partial cross sections) of the phosphine (PH3) by direct and dissociative electron ionization have been evaluated by using modified Jain-Khare semi-empirical approach. To the best of my knowledge, no other data (experimental and/or theoretical) of differential cross sections is available till now for comparison. Partial and total integral ionization cross sections were also evaluated for PH3. Integral ionization cross-sections show good agreement with available experimental/or theoretical data. Ionization rate coefficients corresponding to partial ionization cross-sections have also been calculated by the Maxwell-Boltzmann distribution of energy. (C) 2014 Elsevier B.V. All rights reserved.
