Title: Communication: Rovibrationally selected study of the N{sub 2}{sup +}(X; v{sup +}= 1, N{sup +}= 0-8) + Ar charge transfer reaction using the vacuum ultraviolet laser pulsed field ionization-photoion method

Abstract

By employing an electric field pulsing scheme for vacuum ultraviolet laser pulsed field ionization-photoion (PFI-PI) measurements, we have been able to prepare a rovibrationally selected PFI-PI beam of N{sub 2}{sup +}(v{sup +}= 1, N{sup +}) with not only high intensity and high quantum state purity, but also high kinetic energy resolution, allowing absolute total cross sections [{sigma}(v{sup +}= 1, N{sup +})] for the N{sub 2}{sup +}(X; v{sup +}= 1, N{sup +}) + Ar, N{sup +}= 0-8 charge transfer reaction to be measured at center-of-mass collision energies (E{sub cm}) down to thermal energies. The {sigma}(v{sup +}= 1, N{sup +}= 0-8) values determined at E{sub cm}= 0.04-10.00 eV are in good agreement with the theoretical predictions based on the Landau-Zener-Stueckelberg formulism. Taking into account the experimental uncertainties, the {sigma}(v{sup +}= 1, N{sup +}), N{sup +}= 0-8, measured at E{sub cm}= 1.56 eV are found to be independent of N{sup +}.
