Abstract
- M. Lettmann et al. -- 6 pags., 5 figs., tab.<br />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.<br />We acknowledge support from the German BMBF Grants No. 05P15RDFN1, No. 05P12RDFN8, and No. 05P15PKFNA; ERC Grant No. MINOS-258567; the Spanish Ministerio de Economía y Competitividad under Contracts No. FPA2014-57196-C5-4-P and No. FIS-2014-53434, the Vietnam Ministry of Science and Technology, as well as from the Science and Technology Facilities Council (STFC).
