Scattering of electrons with perfluoroketone molecules

Per?uoroketone (PFK) molecules have been determined to have extremely low global warming potentials (GWPs) and therefore may have applications in next generation gas discharges and plasma reactors [Kesari et al, Patent no. US 6540930B2 (2003)] and can replace SF$_{\mathrm{6}}$ for various applications. In this work elastic and inelastic cross sections for electron scattering from per?uoroketone (PFK) molecules, C$_{\mathrm{x}}$F$_{\mathrm{2x}}$O (x $=$ 1-6) are reported from the ionization potential to 5 keV using the Spherical Complex Optical Potential formalism [1]. The ionisation cross sections are are derived using the Complex Scattering Potential-ionization contribution (CSP-ic) method and are found in good agreement with previous data. We also describe low energy calculations (below 15 eV) using the ab-initio R-matrix [2] to evaluate resonances, differential and total cross sections.
