Electron attachment to SF6 and lifetimes of SF6- negative ions [PDF]
, 2008 We study the process of low-energy electron capture by the SF6 molecule. Our approach is based on the model of Gauyacq and Herzenberg [J. Phys. B 17, 1155 (1984)] in which the electron motion is coupled to the fully symmetric vibrational mode through a ...

The role of multi-photon dissociation in TEA CO2 lasers pulse shaping [PDF]
مجله علوم و فنون هستهای, 2023 In this research, temporal variations in intense TEA CO2 laser pulses passing through SF6 gas-filled cells with a pressure of 10- 150 mbar have been characterized at different energy fluences and gas pressures.
