Data Group [CO-rot]: Ogloblina P, Tejero-del-Caz A, Guerra V and Alves L L, ''Electron impact cross sections for carbon monoxide and their importance in the electron kinetics of CO2-CO mixtures'' 2020 Plasma Sources Sci Technol. 29 015002.
CO-rot is a set of rotational excitation cross sections by electron impact, for transitions CO(X,v=0,J) --> CO(X,v=0,J+1) (J=0,1, … ,16), which complements the COMPLETE set of CO cross sections, available in this database under group CO. The cross sections were based on the work of Hake R D and Phelps A V, ‘’Momentum-transfer and inelastic-collision cross sections for electrons in O2, CO, and CO2’’ 1967 Phys. Rev. 158 70. For the first five rotational excitations, the cross sections were adjusted near the threshold in order to yield an effective momentum-transfer cross section similar to that of Land J E 1978 J. Appl. Phys. 49 5716. For the other transitions, we used the analytical expression proposed by Hake and Phelps for a dipole moment of 4.4e-2 (in units of ea_0).
Calculations using these cross sections should include inelastic-stepwise and superelastic transitions between rotational states CO(J=0), CO(J=1), … , CO(J=17), 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=0)^17 g_J exp[-E_J/(k_B T_g)]. At T_g=300K, these populations are n_0/N=9.74E-03 n_1/N=2.87E-02 n_2/N=4.60E-02 n_3/N=6.10E-02 n_4/N=7.28E-02 n_5/N=8.11E-02 n_6/N=8.57E-02 n_7/N=8.68E-02 n_8/N=8.48E-02 n_9/N=8.02E-02 n_10/N=7.36E-02 n_11/N=6.57E-02 n_12/N=5.72E-02 n_13/N=4.85E-02 n_14/N=4.02E-02 n_15/N=3.25E-02 n_16/N=2.57E-02 n_17/N=1.99E-02.
