Abstract
Electron spectroscopy using intersecting electron and atomic beams was used for the first time to measure the electron excitation function of the (1s2s2p)4P1/2,3/2 autoionization states of the lithium atom in the range of collision energies between the level excitation threshold and 90 eV with an energy resolution better than 0.4 eV and a magic observation angle θ=54.7°. An analysis of the intense near-threshold structure observed revealed for the first time that autodetachment states of the negative lithium ion having excitation thresholds of 58.2±0.1 and 59.5±0.1 eV exist in the autoionization energy range.
