Triaxial deformation of neutron-rich Zr nuclei explored by high-resolution in-beam γ-ray spectroscopyMoon, B.Korten, W.Wimmer, K.Doornenbal, P.Rodríguez, T.

The experiment was carried out at the Radioactive Isotope Beam Factory in RIKEN, using nucleon removal reactions of radioactive Nb ions to produce 108Zr and 110Zr. Emitted γ rays from the excited states were measured by the High-resolution Cluster Array at RIBF (HiCARI) and lifetimes were extracted from the observed line shapes caused by relativistic Doppler-shift effects. In addition to the new lifetime information, the precision of the E(21+) and R4/2=E(41+)/E(21+) values of 110Zr could be significantly improved. The low-lying 22+ states in both nuclei are also newly observed, which are indicative of the triaxiality. The various physical quantities were compared with theoretical models to investigate the collectivity in Zr isotopes towards N=70. Together the experimental and theoretical results point at a reduction of the axial deformation while triaxial collectivity increases.This work was carried out at the RIBF operated by RIKEN Nishina Center and Center for Nuclear Studies in the University of Tokyo.
