Abstract
The reaction O-16 + Au-197 has been studied at a bombarding energy of 80 MeV. A group of 5.20 MeV alpha particles with a half-life of about 90 m has been found in coincidence with characteristic X-rays of At an d with gamma-rays. The gamma-ray energies fit predicted energies for s uperdeformed band. The data are interpreted as due to formation of a l ong-lived isomeric state which decays by low energy alpha-particles to SD band. The calculated probability for decay via a barrier of a supe rdeformed nucleus was found to be consistent with the experimental res ults.
