Abstrakt: High-spin states in 197Bi were studied with the AFRODITE γ-ray array at iThemba LABS using the 181Ta( 22Ne, 6 n) reaction at a beam energy of 125 MeV. A new shears band was found and linked to the low-lying states in 197Bi. Its dynamic moment of inertia, $ \Im^{{(2)}}_{}$, is considerably larger than the $ \Im^{{(2)}}_{}$ of the shears bands in the neighbouring Pb isotopes. This is probably a result of the involvement of an additional high- K h9/2 proton orbital. [ABSTRACT FROM AUTHOR]
