We present the experimental excitation function for the 7α de-excitation of ²⁸Si nuclei excited to high excitation energies in the collisions of 35 MeV/nucleon ²⁸Si with ¹²C 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.
