Data Group [O2]: G. Gousset, C.M. Ferreira, M. Pinheiro, P.A. Sá, M. Touzeau, M. Vialle and J. Loureiro ''Electron and heavy-particle kinetics in the low pressure oxygen positive column'' 1991 J. Phys. D 24 290; L.L. Alves, P. Coche, M.A. Ridenti and G. Guerra ''Electron scattering cross sections for the modelling of oxygen-containing plasmas'' 2016 Eur. Phys. J. D 70 124. The complete cross sections set was compiled from A.V. Phelps 1985 Technical Report 28 JILA Information Center Report, University of Colorado, Boulder, Colorado, USA.
The cross sections were originally limited to 40 eV kinetic energy, and were later extended to 1 keV using information from the databases PHELPS and BIAGI-v8.9. The cross section for the excitation of O2(a1Deltag) was extended up to 200 eV using the results of K.J. Wakiya 1978 J Phys B 11 3913, and extrapolated up to 1 keV. When this complete set is used in a two-term Boltzmann solver (choosing a linear interpolation scheme), it yields calculated swarm parameters in good agreement with measurements for E/N values between 10 and 1000 Td. For E/N < 10 Td, the set must be further completed to include rotational excitation mechanisms (see below), in order to reproduce measured swarm data.
IMPORTANT NOTICE ABOUT ROTATIONAL EXCITATION
This set is to be completed with the rotational cross sections for transitions O2(X,v=0,J) --> O2(X,v=0,J+2) (J=1,3,.,29), available in this database under group Oxygen > O2-rot (see O2-rot description for more details). When the full cross section set for O2 (containing momentum-transfer, dissociative attachment, and electronic excitation and ionization from ground-state) and O2-rot (including the rotational excitation / deexcitation to/from the O2(J=1), O2(J=3), ., O2(J=29) states) are used in a two-term Boltzmann solver, one obtains calculated swarm parameters in good agreement with measurements over a large range of E/N values (1e-4 to 1000 Td).
