摘要：

In several recent measurements the symmetric fission of Mg-24 has been reported. In this paper the results of a search for similar processes in Si-28 and S-32 are presented. In contrast to the results for Mg-24, no evidence is seen for the fission of Si-28 to O-16 + C-12 or S-32 to O-16 + O-16 following inelastic excitation. However, these processes are observed to occur following pickup onto Mg-24. The results are consistent with a simple model of the fission process developed by Harvey and suggest the existence of large scale cluster structure in all three nuclei.
