Fragmentation behaviour of nonrotating "superheated" small Ni-n, n=4-5 clusters have been studied with molecular dynamics simulations using Gupta potential energy function. Survival probabilities and global fragmentation rate constants are computed and analysed as functions of internal energy and of the size of the clusters.
