[en] Nuclei in the Yb region (A ≈ 170) constitute some of the best examples of normal-deformed axially symmetric rotors known. The aim of the experiment was to study high-K states, rotational and vibrational band structures and the evolution of collectivity along the Yb isotopic chain. Identification of the high-K states and associated bands and lifetime measurements for possible longer-lived isomers (T_1/2 > 100 ns) is one of the objectives. The band structures built on the high-K states and the branching ratios for the decay of the levels in these rotational bands would also allow for configuration assignments
