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