Electron attachment to oxygen in nitrogen buffer gas at atmospheric pressure

Electron attachment to chlorinated alcohols

“…These studies are of particular interest, since electrons despite the fact that their energy is less than the ionization energy of many molecules, are reactive in contact with various substances ranging from small molecules such as O 2 [3] and ending at the components of DNA [4].…”

Effects of small thundercloud electrostatic fields on the ionospheric density profile

“…where k O 2 and k N 2 are three-body rate constants for reaction (R3) in Table 1 when M represents O 2 and N 2 , respectively. The values of k 3att at very low values of̄are obtained by extrapolating k O 2 and k N 2 values given in Hurst and Bortner [1959], Chanin et al [1962], Kučera et al [2013], and Shutov et al [2013]. When ≥ 0.13 eV, the results from the previous studies indicated that the relationship between ln k 3att against lnī s approximately linear.…”

“…When , the results from the previous studies indicated that the relationship between ln k 3att against is approximately linear. Finally, k 3att can be approximately fitted by the following piecewise formula: A comparison between this formula with the experimental data and calculations available in the literature [e.g., Hurst and Bortner , ; Chanin et al , ; Davies , ; Kossyi et al , ; Hagelaar and Pitchford , ; Kučera et al , ; Shutov et al , ] is given in Figure . The fitting formula matches well with experimental data and theoretical calculations, so it is used for our study.…”

“…A comparison of the fitting formula (equation ) of the three‐body rate constant as a function of average electron energy or as a function of E / N with experimental and theoretical studies available in the literature [e.g., Chanin et al , ; Hurst and Bortner , ; Davies , ; Kossyi et al , ; Hagelaar and Pitchford , ; Kučera et al , ; Shutov et al , ]. The dependence of on E / N can be obtained from the work of Moss et al [].…”

“…It should be noted that the three-body electron attachment process is already operative at thermal electron energies as shown in (R2). A review of the existing literature on the rate constant of this process [e.g., Chanin et al, 1959;Lennon and Mulcahy, 1961;Davies, 1983;Raizer, 1991;Kossyi et al, 1992;Fridman and Kennedy, 2004;Kučera et al, 2013] leads us to conclude that in the absence of electric field, the average thermal k 0 3att from different sources is about 11.7 ×10 −44 m 6 /s.…”
