Abstract
High-spin states of the odd–odd \({}^{194}\)Bi nucleus have been studied by means of nuclear spectroscopy for the first time. Two low-lying rotational bands were observed. The positive-parity band built on a short-lived isomeric state 633 keV above the \(\alpha \) and \(\beta \) decaying long-lived (10\(^-\)) state is assigned a \({\pi i_{13/2} \otimes \nu i_{13/2 }^{-1}}\) configuration, while the other band is attributed to the \({\pi h_{9/2} \otimes \nu i_{13/2 }^{-1}}\) configuration. Both of these bands are assumed to have oblate shape. Three band-like structures composed predominantly of \(\Delta I = 1\) transitions were also found. One of the shears band candidates is firmly linked to the lower lying level structures whereas for the other two links to lower-lying structures remain missing.
