| Description |
The electron impact ionization studies of the fluorocarbons are important due to their immense industrial applications. For their fruitful use and applications and to comprehend their role in the atmosphere, it is important to understand their fundamentalinteraction with electrons and photons particularly in the energy regime of 10 - 100 eV. Determination of absolute cross sections and threshold energies for various ion formation channels is essentialfor these studies. In my talk, I will present the extraction of ionization threshold frommeasurements for various ion fragmentchannels observed in electron impact ionization of CF4 and 1, 1-C2H2F2. We observed a short lived resonance structure in CF2+ channel from both the molecules.I will discuss these findings along with the measured absolute partial ionization cross section. |
