Data Group [O]: 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 cross section set was obtained from R.R. Laher and F.R. Gilmore 1990 J. Phys. Chem. Ref. Data 19 277. These data, for electron collisions with atomic oxygen, complement the COMPLETE set of O2 cross sections (available in this database under group O2) for use in a chemistry scheme.
Here, O(1D) and O(1S) are also targets (in the superelastic collisions e+O(1D,1S) --> e+O(3P)). Thus, when adopting this cross section set in Boltzmann calculations, one should also take the elastic momentum-transfer cross section for O(1D) and O(1S) (available in this database under group O-elec).

Data Group [O2-rot]: E. Gerjouy and S. Stein, ''Rotational Excitation by Slow Electrons'' 1955 Phys. Rev. 97 1671.
O2-rot is a set of rotational excitation cross sections by electron impact, for transitions O2(X,v=0,J) --> O2(X,v=0,J+2) (J=1,3,.,29), which complements the COMPLETE set of O2 cross sections, available in this database under group O2.
Calculations using these cross sections should include inelastic-stepwise and superelastic transitions between rotational states O2(J=1), O2(J=3), .. , O2(J=29), assuming a Boltzmann distribution for their populations:
n_J/N = (g_J/P_rot) exp[-E_J/(k_B T_g)] with P_rot = Sum_(J odd)^31 g_J exp[-E_J/(k_B T_g)] [cf. R.D. Hake Jr. and A.V. Phelps 1967 Phys. Rev. 158 70]. At T_g=300K, these populations are n_1/N=4.09E-02 n_3/N=8.91E-02 n_5/N=1.24E-01 n_7/N=1.41E-01 n_9/N=1.41E-01 n_11/N=1.27E-01 n_13/N=1.06E-01 n_15/N=8.13E-02 n_17/N=5.81E-02 n_19/N=3.88E-02 n_21/N=2.42E-02 n_23/N=1.42E-02 n_25/N=7.82E-03 n_27/N=4.05E-03 n_29/N=1.97E-03 n_31/N=9.04E-04.

Data Group [O2-vib]: A. Annušová et al, ''Kinetics of highly vibrationally excited O2(X) molecules in inductively-coupled oxygen plasmas'' 2018 Plasma Sources Sci. Technol. 27 045006.
O2-vib is a set of vibrational excitation cross sections by electron impact, for transitions O2(X,v) --> O2(X,v’) (0 <= v < v’ <=41), O2(X, v=0-6) --> O2(a) and O2(X,v=0-8) --> O2(b), which complements the COMPLETE set of O2 cross sections (available in this database under group O2) for use in a chemistry scheme.
The cross sections for e + O2(X,v) --> e + O2(X,v’) (labeled ''Vibrational'') were obtained from V. Laporta, R. Celiberto and J. Tennyson 2013 Plasma Sources Sci. Technol. 22 025001. These cross sections are intended for calculating electron rate coefficients, to be used in a chemistry model where the full-manifold of electron-vibrational mechanisms is included. Note that the cross sections for transitions O2(X,v=0) --> O2(X,v’=1-4) do NOT correspond to those adopted in the COMPLETE set of O2 cross sections, available in this database under group O2. The definition of a coherent set of data for these transitions is currently in progress.
The cross sections for e + O2(X,v) --> e + O2(a,b) (labeled ''Excitation'') were calculated using Franck-Condon factors applied to the cross sections for e + O2(X,v=0) -> e + O2(a,b) proposed by A.V. Phelps 1985 Technical Report 28 JILA Information Center Report, University of Colorado, Boulder, Colorado, USA.
