The meltinglike phenomenon in Ni{sub n}, n = 19,20,55, clusters is studied using microcanonical molecular dynamics simulations. The interaction between the atoms in the clusters is modelled by a size-dependent Gupta-like potential that incorporates many-body effects. The clusters display the usual'' stages in their meltinglike transition, which characterize also Lennard-Jones (e.g., noble gas) and ionic clusters. In addition, Ni{sub 20} passes through a so-called premelting stage found earlier also for Ni{sub 14}. 11 ref., 3 figs.
