摘要： The mean coordination numbers of some nickel clusters have been calculated for some proposed geometric structures for them, and their ionization potentials are obtained using an effective coordination-number model. It is shown that the mean effective-coordination number of all atoms of a cluster should be taken as a parameter to describe the d-band width of the cluster instead of mean effective coordination number of surface atoms.
