“…New experimental determinations of the cross sections by Allan [9,13] have since appeared, which differ near threshold from the experiments [5,7,8] with which we originally compared and which do not show the dramatic suppression of peaks near threshold that some earlier experiments suggested. These facts prompted the present study, in which the nuclear dynamics problem is treated with a more elaborate nonlocal resonance model that should be better able to treat the threshold region.…”

“…This feature can be understood by taking into account the fact that the barrier penetration factor introduced in our equations will affect the cross sections only at electron energies with momenta k that are lower than the local momentum k(R) in Eq. (7). As the energy of the vibrational level from which the dissociation takes place increases, the threshold energy, and thus the incident electron momentum needed for the the dissociation to occur, decreases.…”

“…NO is also used as a plasma gas and plays important functional roles in a variety of physiological systems. Although there have been a number of experimental studies on the low-energy behavior of the electron-NO collision cross sections [1][2][3][4][5][6][7][8][9], relatively little has been done on the theoretical front [10,11], particularly in the energy region below 2 eV, which is dominated by negative ion resonances. Calculations in this energy range were initiated in our previous study (Zhang et al [12]), which presented ab initio determinations of elastic and vibrational excitation cross sections using the local complex potential or "boomerang" model, with resonance parameters extracted from electronic fixed-nuclei variational scattering calculations.…”

Nonlocal model of dissociative electron attachment and vibrational excitation of NO

We present the results of an ab initio study of elastic scattering and vibrational excitation of NO by electron impact in the low-energy (0-2 eV) region where the cross sections are dominated by resonance contributions. The 3 Σ − , 1 ∆ and 1 Σ + NO − resonance lifetimes are taken from our earlier study [Phys. Rev. A 69, 062711 (2004)], but the resonance energies used here are obtained from new configuration-interaction studies. Here we employ a more elaborate nonlocal treatment of the nuclear dynamics, which is found to remedy the principal deficiences of the local complex potential model we employed in our earlier study, and gives cross sections in better agreement with the most recent experiments. We also present cross sections for dissociative electron attachment to NO leading to ground state products, O − ( 2 P) + N( 4 S). The calculations show that, while the peak cross sections starting from NO in its ground vibrational state are very small (∼ 10 −20 cm 2 ), the cross sections are extremely sensitive to vibrational excitation of the target and should be readily observable for target NO molecules excited to ν = 10 and above.

“…[53] ICSs for excitation to nine electronic states of NO [54] were derived from measurements by Mojarrabi et al [55] and by Brunger et al [56] ICSs for the vibrational excitations (0!1), (0!2), and (0!3) of the ground electronic state of NO were derived [57] from measurements in Belgrade. [58] Flinders [59] and Canberra. [60] ICSs for excitation of each of levels 0-7 of the A 1 P state of CO were interpolated from BEf-scaled values given in Table 7 of the article by Kato et al [61] The efficacy of those ICSs was based on DCS measurements reported in references.…”

LXCat is an open‐access platform (http://www.lxcat.net) for curating data needed for modeling the electron and ion components of technological plasmas. The data types presently supported on LXCat are scattering cross sections and swarm/transport parameters, ion‐neutral interaction potentials, and optical oscillator strengths. Twenty‐four databases contributed by different groups around the world can be accessed on LXCat. New contributors are welcome; the database contributors retain ownership and are responsible for the contents and maintenance of the individual databases. This article summarizes the present status of the project.

“…It is isoelectronic with NO, which has been the focus of several recent theoretical [17,18] and experimental [19][20][21][22] studies, and might be expected to display similar behavior in its interaction with low-energy electrons. In particular, the addition of an electron to CF results in three anion states of 3 Σ − , 1 ∆ and 1 Σ + symmetry, which by analogy with NO − (and O 2 ) are expected to be separated by only a few eV.…”

Resonant electron-CFcollision processes

2005

View full text Add to dashboard Cite

Electronic structure methods are combined with variational fixed-nuclei electron scattering calculations and nuclear dynamics studies to characterize resonant vibrational excitation and electron attachment processes in collisions between low-energy electrons and CF radicals. Several low-lying negative ion states are found which give rise to strong vibrational excitation and which are expected to dominate the low-energy electron scattering cross sections. We have also studied several processes which could lead to production of negative ions (F − and C − ), however, in contrast to other recent predictions, we do not find CF in its ground state to be a significant source of negative ion production when interacting with thermal electrons.
