| description | Electron collision cross-sections of <i>c</i>-C<sub>4</sub>F<sub>8</sub> were investigated at low energies by using the R-matrix method. The static exchange (SE), static exchange with polarization (SEP), and close-coupling (CC) models of the R-matrix method were used for the calculation of the scattering cross-section. The shape resonance was detected with all the models at around 3~4 eV, and a Feshbach resonance was detected with the SEP model at 7.73 eV, in good agreement with the previous theoretical calculation. The resonance detected was also associated with the experimental dissociative electron attachment of <i>c</i>-C<sub>4</sub>F<sub>8</sub>, which displayed the resonances at the same energy range. The cross-sections calculated are important for plasma modeling and applications. |
