“…In order to discuss the observed thresholds, firstly in pure solid CO 2 , we list the threshold energies of the same ions but in the gas phase ͑see Table II͒ obtained by electron impact ionization, as reported by different groups. 13,[18][19][20][21][22][23][24] The first three thresholds of O ϩ ions in the gas phase are at ϳ19 and 20, 18-21 ϳ22.5, 21,23 and 24.5 eV, 21 respectively. In the solid phase ͑Table I͒ the observed thresholds of the O ϩ ions are at 21.5Ϯ0.5 eV and 25Ϯ0.5 eV.…”

“…4.2 PROCESSUS CONDUISANT À LA FORMATION DES IONS 02 . La molécule CO2 étant linéaire, il est surprenant d'observer l'existence d'ions 0+ dans le spectre de masse des produits issus de la collision, bien que l'ion S+ ait été observé par photoionisation [8] à partir de la molécule CS2, qui est également linéaire. La présence de la particule lourde He* peut expliquer une modification de la géométrie de CO2 au cours de la collision et l'apparition d'une liaison entre les deux oxygènes.…”

“…The ionization potentials of methylstannyl radicals have been measured using a doublepulsed mass-spectrometric method in which the radicals were formed by the impact of electrons on hexamethylditin (1487). The direct double-ionization potentials of CS2 to CS22+ and CO2 to C022+ were observed in a mass spectrometer (1488).…”
