| Abstract: | Vibrational excitation of SF6 by a 10.6 μm CO2 laser is shown to reduce lifetimes for SF6 dimers in supersonically expended flows. A possible utility of this phenomenon in controlling condensation rates to separate isotopes is discussed, and a kinetic analysis of the expected isotopic composition of SF6 in a supersonically expanded stream is presented. |
