  Long-lived high-spin super- and hyper-deformed isomeric states, which exhibit
themselves by abnormal radioactive decays, have been observed using the 16O +
197Au and 28Si + 181Ta reactions. They make it possible to understand the
production, via secondary reactions, of the long-lived superheavy element with
Z = 112 and of the abnormally low energy and very enhanced alpha-particle
groups seen in various actinide sources. They might also explain some puzzling
phenomena seen in nature.
