4 (NBS Author: Donald Rapp, Paula Englander‐Golden. 1. Introduction. Cross section data on collision processes of electrons with nitrogen molecules (N 2) and singly ionized nitrogen molecules (N 2 +) are important in studying low-temperature plasmas in nature and industrial techniques of gaseous electronics and plasma processing.

In the field of thermonuclear fusion research, the use of N 2, Ne, Ar, and other gases is being by:   Cross section data have been compiled from the literature (to the end of ) for electron collisions with water (H 2 O) molecules.

All major collision processes are reviewed including: total scattering, elastic scattering, momentum transfer, excitation of rotational, vibrational, and electronic states, ionization, electron attachment. A Monte-Carlo procedure has been used to evaluate elastic and vibrationally inelastic momentum transfer cross-sections which are consistent with measured electron swarm transport coefficients in SiH 4 and SiD 4 at low E/N(ratio of applied electric field to gas number density).

In each molecule the elastic cross-section has a Townsend minimum between and eV electron energy. The elastic cross section shows a number of resonance features, which we classify according to symmetry and analyze in relation to available experimental data.

Electron-impact Bibliography of low energy electron collision cross section data book cross sections are obtained for the 1 3 B 1u (T) and 1 1 B 1u (V) states arising from the π→π * transition, as well as for eight other low-lying excited.

Absolute total cross sections for negative‐ion formation in several gases (CO, NO, O2, CO2, N2O, SF6, and H2) by electron impact have been measured in a total ionization tube. Both dissociative attachment and ion‐pair formation have been measured, with careful attention paid to complete collection of the negative ions.

Possible errors due to scattered electrons and energy. Various types of sensors have been studied to detect volatile organic compounds (VOCs). Here, we developed a sensor that operates with a novel mechani. We describe the development of a consistent set of low-energy electron collision cross sections for trifluoromethane, CHF 3.

First-principles calculations are used to obtain key elastic and inelastic cross sections. These are combined with literature values of the ionization cross section and with vibrational excitation cross sections obtained from the Born approximation to form a preliminary.

The hydroxyl radical, OH, is a key component of many plasmas include atmospheric ones, particularly if the air is humid [1–7] or near liquid water [8–10], and plasmas formed during combustion [11, 12].Models of such plasmas require rates or cross sections for key processes occuring in the plasma but for OH these are largely unknown [] and hence are absent from major data.

ionization cross sections, and high energy electron. As referred to in sectionthe validity of the two-term approximation to solve the electron Boltzmann equation is questionable when the magnitude of the inelastic collision cross sections exceeds that of the elastic momentum transfer collision cross section [66, 67], as is the case here for electron energies below ~ eV.

Laboratory Astrophysics Division, NBS, Boulder, CO. Distorted-wave Born approximation (DWBA) calculations are reported for singly-differential and total cross sections for the electron impact ionization for atomic hydrogen at 25, 40, 60, and eV.

The theory is compared with available experiments. At all the energies except 25 eV the theory predicts a lower singly-differential cross section for the low-energy side of the secondary.

D/µ as a function of E/N is presented for electron swarms in ethane, propane, propylene and cyclopropane, and momentum transfer and vibrational excitation cross-sections for electron energies between about and eV are evaluated for these molecules.

In each species, vibrational excitation is efficient. Ethane, propane and propylene have a minimum in the momentum transfer cross-section. In this section we present a systematic study which gives eigenphase sums, elastic differential cross sections (DCS) and integral cross sections (ICS) for low-energy electrons collisions HOOCl, HOClO and HClOO isomers in the range from to 10 eV.

We also present estimated dissociative electron attachment cross sections for the HClO 2 isomers. Data Providers; Services; Blog; About; Contact us; Search.

The data are taken at the incident electron energies of, and eV and for scattering angles of 10 deg. deg. The measurements involve. The cross section for dissociative recombination when a protonated water molecule captures an electron increases by about 5 orders of magnitude as the center-of-mass kinetic energy decreases from 30 eV to eV.

40 The EC cross section for D + (D 2 O) 2 increases by about three orders of magnitude when the ion-electron center-of-mass kinetic. A knowledge of electron collision cross sections is important for this and other applications.

However, there appear to be no previous published studies of electron collisions with neutral C 2. This would seem to be in contrast with the C − 2 ion for which a number of studies performed using the ASTRID storage ring are available (Andersen et. Abstract. A study is made of low-energy electron-impact single ionization of ground-state helium.

The time-dependent close-coupling method is used to calculate total integral, single differential, double differential, and triple differential ionization cross sections for impact electron energies ranging from 32.

Absolute cross sections (CSs) for electronic excitation by low-energy electron (LEE) scattering, from condensed thymidine (dT) in the 6–18 eV incident energy range, were measured by high-resolution electron energy loss spectroscopy (HREELS). Various electron energy loss (EEL) spectra were acquired using 1 ML PCCP HOT Articles.

Bibliography of low energy electron and photon cross section data (through December ). [Lee Joseph Kieffer; United States. Laboratory Astrophysics Division.]. Perhaps the most widely used excitation cross sections have been the phenom- enological calculations of Green and Barth.*14' The most direct method for studying electron inelastic collision cross sections is by means of an electron scattering apparatus in which a beam of electrons of known current and geometry is scattered by a gas of known.

The Ar (Ramsauer gas) has a minimum cross section for electron-neutral collisions at low electron energy range below 1 eV, while the He (non-Ramsauer gas) has no minimum cross section in this electron energy range as indicated in Fig.

2e 38, Due to the collision cross section of Ar, the electron heating rate and EEPF strongly depend on the.The long-range collision interaction transfer momentum between ions and electrons is at a rate which depends on the collision frequency which relies on the corresponding cross section.

Low dispersion angles corresponding to large impact parameters give the larger contribution to in equation ().An ion-atom merged-beams technique is being used to measure total absolute electron-capture cross sections for multicharged ions in collisions with H (or D) in the energy range between and eV/amu.

Comparison between experiment and theory over such a large energy range constitutes a critical test for both experiment and theory.
