Abstract

A variety of oxygen-containing diatomic dications XO2+ can be produced in the gas phase by prolonged high-current 160- 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 ∼10-5s. Examples provided here include ion mass spectra of AsO2+, GaO 2+, Sb02+ Ag02+ CrO2+ and BeO 2+. A detailed theoretical study of the diatomic dication system BeO2+ is also presented.
