Negative Hydrogen Ion

An expression is derived for the lifetime of a negative ion in a weak and static electric field. Using this expression, existing experimental data are analyzed to improve the empirical value of the electron affinity of the negative hydrogen ion by an order of magnitude.

Three Body

The normalized electron affinity of the hydrogen atom, is the fundamental measure of anionic electron correlation. The three-body H (−) and AB(−) systems analogous to Efimov three-body bosons support multiple excited states. The first complete set of ground state electron affinities of the main group atoms and homonuclear diatomic molecules are reported using the Hylleraas variational binding energy of the hydride anion. Thermal electron affinities and activation energies for the formation of the 27 bonding states of O 2(−) are reported from electron capture detector and atmospheric pressure negative ion mass spectrometry. These are iterated through magnetron, flame, swarm, electron impact, photodetachment, and negative ion photoelectron spectra to obtain more precise self-consistent values. Electron affinities for NO are similarly reported. These data are used to calculate Herschbach ionic Morse Person electron curves for the 54 O 2(−) and 87 NO (−) states predicted by adiabatic correlation rules. A new ground state adiabatic electron affinity of SF6 3.00(10) eV is determined from negative ion mass spectra.

Peak Cross Section

The formation of positive and negative ions in carbon dioxide has been investigated by means of a Lozier apparatus. The negative ion process was interpreted as CO 2 + e → CO( X 1 Σ + ) + O - (2 P 0 ). The (peak) cross-section for electron attachm ent was found to be 5·07 ± 0·5 x 10 -19 cm 2 at 7·8 eV, and the ionization cross-section reached a m axim um value of 6·80 x 10 -16 cm 2 at 85 eV. Measurements of the electron affinity of oxygen by the normal electron impact method yielded a value of 1·6 ± 0·2 eV for O - ions formed with an initial kinetic energy of 1·8 eV. It is shown that this apparent value of electron affinity must be corrected, because of the initial kinetic energy of the ions and the energy spread of the source electrons, and then yields a value of 1·2 ± 0·3 eV.
