Abstract

A minimal lifetime of microseconds is displayed by the dication GeH²⁺, which has been detected for the first time as the product of charge-stripping experiments at 8 kV involving [GeH₂]⁺ and O₂. Coupled-cluster calculations suggest that XH²⁺ (X = Si, Ge) are both metastable with respect to internal conversion and dissociation via X⁺ and H⁺. The picture shows a potential energy surface scan of GeH²⁺ and the corresponding Coulomb repulsion asymptote.
