摘要：

An excited superdeformed (SD) band has been observed in 190Hg which decays to the lowest-energy (yrast) SD band rather than to the less deformed states as observed in most known SD bands in the A approximately 150 and A approximately 190 regions. The most plausible interpretation of this very unusual decay pattern associates this band with a collective structure built on an octupole-vibrational phonon in the SD well.
