SOME OXYGEN IONS FORMED AT HIGH PRESSURES IN A MASS SPECTROMETER

Abstract

The oxygen ions formed by electron bombardment and collision processes in the mass spectrometer at pressures of about 10⁻³ mm Hg are examined. Mass spectrum lines due to O⁺, [Formula: see text], [Formula: see text], and O⁺⁺ as well as Aston bands due to O⁺, [Formula: see text], and [Formula: see text] are found. Processes leading to these species, as well as abundances and appearance potentials, are considered.
