Good Agreement

Measurements of the σ10 cross section for a beam of Ar+ ions of energies between 30 and 120 keV passing through a thin target of the rare gases show good agreement with the few previous measurements in this energy region.

Positive Ion

The cross section σ−+ for double electron detachment from Cl− in a single collision with a rare gas atom has been measured between 12.5 and 122.5 keV. The magnitude of these cross sections shows that there is a good probability that a second electron will be emitted in collisions that detach one electron, particularly with light targets. The centre-of-mass cross section decreases with increasing target mass, but the variation is less than that for F− and O− double electron detachment cross sections.

Long Lifetime

Detachment cross-sections for collisions of O - , Cl - , F - ions with rare-gas atoms are measured between 50 and 4000 eV incident-ion energy. The negative ions are produced (i) by thermal dissociation of molecules at a filament, followed by radiative attachment into the ground state; (ii) by electron bombardment of molecules, giving ions previously believed to be in an excited state of long lifetime. In every case the detachment cross-sections for the ions produced in the two ways are the same, so that we must conclude either (i) that the excited state has a short lifetime which is unlikely but not impossible, or (ii) that no excited state exists, and that the appearance potentials for ions believed to be in this state must be explained by another process, such as the formation of O neutrals followed by radiative attachment at the source filament.
