“…The overall uncertainty can approach this level by increasing counting statistics, allowing the systematic study of subtle changes of the nuclear radius along sequences. Na-like ions can be produced in large abundance in EBIT devices, offering the possibility of conducting measurements on radioactive isotopes at existing rare-isotope beam facilities like the NSCL [37] and TITAN/TRIUMF [38]. Present and next-generation facilities where this method could be implemented are CARIBU [39], ISOLDE [40], FRIB [41], RAON/RISP [42], and MATS/FAIR [43].…”

The difference in mean-square nuclear charge radius of xenon isotopes was measured utilizing a new method based on extreme ultraviolet spectroscopy of highly charged Na-like ions. The isotope shift of the Na-like D1 (3s 2 S 1/2 -3p 2 P 1/2 ) transition between the 124 Xe and 136 Xe isotopes was experimentally determined using the electron beam ion trap facility at the National Institute of Standards and Technology. The mass shift and the field shift coefficients were calculated with enhanced precision by relativistic many-body perturbation theory and multi-configuration Dirac-Hartree-Fock method. The mean-square nuclear charge radius difference was found to be δ < r 2 > 136,124 = 0.269(42) fm 2 . Our result has smaller uncertainty than previous experimental results and agrees with literature values.

“…The 80 Ge nuclei were selected using the A1900 fragment separator [26] and delivered to a gas-cell [27] which is used to stop and thermalize the high-energy beam. The 80 Ge nuclei were extracted from the gas-cell, charge bred in NSCL's electron-beam ion trap [28], and injected into the ReA3 accelerator to be delivered to the experimental setup.…”

Evolution of shape and collectivity along the Ge isotopic chain: The case of Ge80

et al. 2022

The shape and collectivity of 80 Ge were investigated via a sub-barrier-energy Coulomb excitation measurement using the JANUS setup at the NSCL ReA3 facility. The 80 Ge spectroscopic quadrupole moment Qs(2 + 1 ) of the 2 + 1 state was measured for the first time, and the precision of the 80 Ge B(E2; 0 + 1 → 2 + 1 ) transition strength was increased. The experimental Qs(2 + 1 ) value indicates a large, prolate deformation for 80 Ge, which is consistent with large-scale shell-model calculations performed for comparison. These results provide important benchmarks for models that try to describe nuclear shape in neutron rich nuclei near the magic number N = 50.
