Abnormal radioactive decays out of long-lived super- and hyper-deformed isomeric states

Abstract

Long-lived high-spin super- and hyper-deformed isomeric states, which exhibit themselves by abnormal radioactive decays, have been observed using the 160 + 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 α-particles seen in various actinide sources. They may also explain some puzzling phenomena seen in nature.
