Abstract

The formation of diatomic ions of Mo 2+ 2 formed during Ar + sputtering of an molybdenum metal surface, was investigated. A secondary ion mas spectrometer was used to study the diatomic dications in the positive ion mass spectra. It was found that the the diatomic ions of Mo 2+ 2 were observed at high primary current densities for projectile ions of Ar +. The formation of the dications was found to take place by resonant charge transfer in grazing gas-phase collisions between incoming projectile ions of Ar + and sputtered molecular ions of Mo 2+ 2.
