Abstract
Coulombic fission of triply charged strontium atom clusters is studied for previously photoheated clusters by unimolecular dissociation experiments. It is shown that the predominant fission channel depends on the degree of internal excitation of the triply charged parent. Such a result shows evidence of the role played by the entropy in the dynamics of fission process.
