Electron removal during the D.C. discharge afterglow of carbon monoxide

Dissociative recombination and vibrational excitation of CO+: model calculations and comparison with experiment

“…is displayed in figure 6; its thermal value (300 K) is in excellent agreement with the measured values obtained in a merged beam by Mitchell and Hus (1985) and Laubé et al (1998), as well as storage-ring-based (Rosen et al 1998) collision experiments. The rate coefficients of Mentzoni and Donohoe (1968) presented as red circles in the figure are higher than the other Figure 8. DR and state-to-state VE and VdE isotropic rate coefficients of CO + in its ground electronic state, + v i standing for the vibrational quantum number of the target ion.…”

“…Our theoretical results, for all symmetries considered here, are represented by magenta dotted lines. The experimental results are shown as follows: Mitchell and Hus (1985), green dashed line; Rosen et al (1998), black solid line; Geoghegan et al (1991), blue diamonds; Mentzoni and Donohoe (1968), red circles; and Laubé et al (1998), violet squares. The role of each dissociation channel depends on the energy of the incident electron.…”

Electron-Induced Excitation, Recombination, and Dissociation of Molecular Ions Initiating the Formation of Complex Organic Molecules

“…The anisotropic Maxwell rate coefficients for both experiments and theory are reported on Figure 7. The agreement is 44 the maroon line and triangles are the estimates provided by Mitchell and Hus, 42 the turquoise diamonds are the measurements of Mentzoni and Donohoe, 41 the orange square is the experimental rate of Geoghegan et al, 43 and finally the indigo cross is the theoretical estimate of Guberman. 45 very good up to an electron energy close to 1 eV.…”

“…The first experimental results on the dissociative recombination of carbon monoxide was obtained in the late 1960s by Mentzoni and Donohoe in a dc discharge afterglow measurement. This was followed by the merged-beam experiment of Mitchell and Hus in 1985 and by the flowing afterglow experiment of Geoghegan et al in 1991.…”

Influence of multiple scattering on the radiation of relativistic particles in amorphous and crystalline media

“…As far as other studies of CO + recombination are concerned, an early afterglow experiment by Mentzoni and Donohue [9] which yielded results nearly twice the size of those found by Rosen et al, almost certainly was affected by the presence of CO + ((CO) n cluster ions according to Whitaker et al [10]). More recently, a flowing afterglow experiment performed by Geoghegan et al [11], yielded results which were almost a factor of 2 smaller than the storage ring results.…”
