Abstract

A variety of oxygen-containing diatomic dications XO2+ can be produced in the gas phase by prolonged high-current 16O− ion surface bombardment (oxygen ion beam sputtering) of a wide range of sample materials. These gas-phase species were detected by mass spectrometry at half-integer m/z values for ion flight times of the order of ∼10−5 s. Examples provided here include ion mass spectra of AsO2+, GaO2+, SbO2+, AgO2+, CrO2+ and BeO2+. A detailed theoretical study of the diatomic dication system BeO2+ is also presented.
