Abstract

The formation of O⁻ and O2⁻ following electron impact to O3 in the energy range between 0 and 3 eV is revisited using a newly designed trochoidal electron monochromator. The previous observation of a very sharp peak in the O− ion yield at an energy close to zero eV [Phys. Rev. Letters 82 (1999) 5028] is interpreted as an artefact due to multiple reflection of very low energy electrons in the collision chamber of the spectrometer.
