We present a statistical fragmentation study of doubly charged iron and aluminum clusters of less than 60 atoms. At low excitation energies we find that the evaporation of one charged monomer is the most probable decay channel (asymmetric fission). When the excitation energy increases there is a competition between evaporation of a charged monomer and a charged dimer. For higher energies the number of channels increases and the multifragmentation mode appears at about 2.5 eV/atom.
