“…In germanium isotopes, this enhanced collectivity leads to a deformed ground-state configuration in 72 Ge, which is found to be a γ -soft nucleus [39] and shape coexistence appears in both germanium and selenium isotopes with N > 40. The increased collectivity in zinc isotopes with N > 40 continues up to N = 44, as reflected from the measured B(E2 ↓) value in 74 Zn in this work and in Ref.…”

At the radioactive ion beam facility REX-ISOLDE, neutron-rich zinc isotopes were investigated using lowenergy Coulomb excitation. These experiments have resulted in B(E2, 2 74,76 Zn and the determination of the energy of the first excited 2 + 1 states in 78,80 Zn. The zinc isotopes were produced by high-energy proton-(A = 74, 76, 80) and neutron-(A = 78) induced fission of 238 U, combined with selective laser ionization and mass separation. The isobaric beam was postaccelerated by the REX linear accelerator and Coulomb excitation was induced on a thin secondary target, which was surrounded by the MINIBALL germanium detector array. In this work, it is shown how the selective laser ionization can be used to deal with the considerable isobaric beam contamination and how a reliable normalization of the experiment can be achieved. The results for zinc isotopes and the N = 50 isotones are compared to collective model predictions and state-of-the-art large-scale shell-model calculations, including a recent empirical residual interaction constructed to describe the present experimental data up to 2004 in this region of the nuclear chart.

“…Few such cases have been studied by Coulomb excitation. Among them is 72 Ge, 17 where the first excited 0 + level of energy 691 keV lies below the 834 keV first 2 + state. Others are 74 Ge, 18 76 Ge 19 and 96−100 Mo.…”

A relationship between experimental E2 matrix elements and nuclear quadrupole charge deformation and triaxiality is presented. Examples of experimentally determined deformation and triaxiality parameters in various regions of the nuclear chart are specified. The most interesting results were found among transitional nuclei. The first such result from a radioactive beam facility is the identification of a triaxial strongly-deformed low-lying 0 + 2 level in 76 Kr.

“…Their properties are driven by shape coexistence and rapid shape changes all the way from the N = Z line into the A ≈ 70 mass region [1][2][3][4][5][6][7][8][9][10][11][12][13]. On the other side of the nuclear chart, the most neutron-rich selenium and germanium isotopes accessible for experiments are around the magic neutron number N = 50.…”
