摘要：
The kinetic energy dependence of collision-induced dissociation (CID) of Ni2+ and Ni3+ with Xe has been investigated with a guided ion beam mass spectrometer. Interpretation of the CID cross section threshold of Ni2+ allows the binding energy of Ni2+ to be determined as 2.08 +/- 0.07 eV. This value is also confirmed by the CID cross section for Ni3+. This bond energy is well below the range of 3 to 3.5 eV obtained from the photodissociation of Ni2Ar+. The origins of the discrepancy between the two studies are discussed.
