摘要：

The experimental excitation function for the 7 alpha de-excitation of Si-28 nuclei excited to high excitation energies in the collisions of 35 MeV/nucleon Si-28 with C-12 reveals resonance structures. The possibility that these structures may indicate the population of toroidal high-spin isomers such as those predicted by a number of recent theoretical calculations is discussed and the need for further investigations is emphasized.
