August (1978) Electron Attachment in Air and Mixtures of O2 with He, N 2 , and C02 The attachment coefficient rj for the formation of negative oxygen ions in low energy electron swarms was measured in dry air and in mixtures of oxygen with helium, nitrogen and carbon dioxide. The shift of the rj/po2-curves of the mixtures against those for pure oxygen are

Isomerization Energies . Vibrational Frequencies The astrochemically relevant molecules of type HC2nH, C2nH2 and C2nH K (n = 2K4) have been investigated theoretically by means of both standard and explicitly correlated coupled cluster theory. Equilibrium structures and harmonic vibrational frequencies have been calculated for all nine species. Accurate values for the molar

Hydrogen Transfer Low energy electron induced reactions in the four fluorinated acetic acid esters CF3COOCH3, CF3COOC2H5, CF3COOCH2CF3 and CH3COOCH2CF3 are studied by means of a crossed elec- tron-molecular beam experiment and mass spectrometric detection of the anions. All target molecules exhibit a prominent resonance located near 1 eV which is subjected to a variety of unimolecular reactions. The observation of the carboxylate anion CF3COO – .CH3COO – indi- cates rupture of the

Zur Trägerzahlstatistik in Folgen von Elektronenlawinen V o n W E R N E R L E G L E R Institut für Angewandte Physik der Universität Hamburg (Z . Naturforschg. 19 a, 481—483 [1964] ; e ingegangen am 21. Dezember 1963) The distribution function for the carrier numbers of series of electron avalanches is calculated. These series develop in gas discharges if the gap voltage approaches the breakdown potential. The calculation is valid for the case that the distribution function of the avalanches is given by v(n) = (l/n) exp( — njri). The influence of electron

source of production of free electrons. An account of destruction of He metastable atoms present in the flow- stream is given. Changes in the linewidth with or without the electron scavenger and thermalization of the electrons are discussed. The energy dependence for the electron attachment to the molecules 0 2, CHC13, c — C4F8, C7F14, and HBr is investigated. The energy scale for electron attachment processes in relation to the input microwave power is established for He carrier gas. Such processes can be studied by employing the ECR technique from thermal
