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.
