Abstract

γ-ray transitions between low-spin states of the neutron-rich Ge84,86,88 were measured by means of in-flight γ-ray spectroscopy at 270 MeV/u. Excited 61+,41,2+, and 21,2+ states of Ge84,86 and 41+ and 21,2+ states of Ge88 were observed. Furthermore, a candidate for a 31+ state of Ge86 was identified. This state plays a key role in the discussion of ground-state triaxiality of Ge86, along with other features of its low-energy level scheme. A new region of triaxially deformed nuclei is proposed in the Ge isotopic chain.
