    The estimated accuracy of the results is ± 1 % for vdr and ±2% for Dli p.. The data have been analysed by means of a multiterm solution of the Boltzmann equation to provide a set of low energy electron collision cross sections consistent with the transport data. Rutherford Cross-Section By definition the cross-section, 0, for any specified collision process when a particle is passing through a density n2 of targets is such that the number of such collisions per unit path length is n Sometimes a continuum of types of collision is considered, e.g. we consider collisions at.

    Electron diffusion coefficients have been measured in methane and collision cross-sections consistent with these measurements evaluated. These show that vibrational excitation is important at low energies and suggest direct rather than resonance excitation. The momentum transfer collision cross-section rises very s.

    The first part of this thesis presents the measurement of the inclusive cross-section for electron production from heavy-flavour decays in the electron transverse momentum range 7 . Cross section data have been compiled for electron collisions with carbon dioxide (CO 2) molecules, based on 75 references. Collision processes considered are: total scattering, elastic.

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 Cited by:   Cross section data are compiled from the literature for electron collisions with oxides of nitrogen (N x O y) molecules: the species nitric oxide (NO), nitrous oxide (N 2 O), and nitrogen dioxide (NO 2) are explicitly sections are collected and reviewed for total scattering, elastic scattering, momentum transfer, excitations of rotational, vibrational, and.

A bibliography of low energy electron collision cross section data is presented. Only references which report original measurements or calculations of electron collision cross sections are included.

The cross section data for each process are listed by atomic species in order of their atomic number. 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. Various types of sensors have been studied to detect volatile organic compounds (VOCs). Here, we developed a sensor that operates with a novel mechani.

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.

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. 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.
