The bond energy of Ni +2
Abstract
The kinetic energy dependence of collision-induced dissociation (CID) of Ni +2 withi Xe has been investigated with a guided ion beam mass spectrometer. Interpretation of the CID cross section threshold of Ni +2 allows the binding energy of Ni +2 to be determined as 2.08 ± 0.07 eV. This value is also confirmed by the CID cross section for Ni +3. This bond energy is well below the range of 3 to 3.5 eV obtained from the photodissociation of Ni 2Ar +. The origins of the discrepancy between the two studies are discussed.
