摘要

High-spin states in ~(178)Ir were investigated by means of in-beam γ-ray spectroscopy techniques using the multidetector array GASP. Excited states of ~(178)Ir were populated through the ~(159)Tb(~(24)Mg, 5n) fusion-evaporation reaction at E(~(24)Mg) = 131-141 MeV. Several rotational bands were observed. Among them, the πi_(13/2) direct X νi_(13/2) structure has been identified up to spin 36 h. This band exhibits an anomalous signature splitting and a signature inversion around spin 25 h.
