Ab initio computations of strongly deformed nuclei near

BS Hu, ZH Sun, G Hagen, T Papenbrock - Physical Review C, 2024 - APS
Nuclei around N≈ Z≈ 40 are strongly deformed and exhibit coexistence of shapes. These
phenomena have challenged nuclear models. Here, we perform ab initio coupled-cluster …

Angular-momentum projection in coupled-cluster theory: Structure of

G Hagen, SJ Novario, ZH Sun, T Papenbrock… - Physical Review C, 2022 - APS

Nuclear Charge Radii of the Nickel Isotopes

S Malbrunot-Ettenauer, S Kaufmann, S Bacca… - Physical Review Letters, 2022 - APS
Collinear laser spectroscopy is performed on the nickel isotopes Ni 58-68, 70, using a time-
resolved photon counting system. From the measured isotope shifts, nuclear charge radii R …

Surprising Charge-Radius Kink in the Sc Isotopes at

K König, S Fritzsche, G Hagen, JD Holt, A Klose… - Physical Review Letters, 2023 - APS
Charge radii of neutron deficient Sc 40 and Sc 41 nuclei were determined using collinear
laser spectroscopy. With the new data, the chain of Sc charge radii extends below the …
