Ab initio calculation of symmetry-breaking observables

A Belley, B. Romeo, J. Engel +8

Symmetry-violating observables such as the nuclear anapole and Schiff moments provide sensitive probes of the fundamental symmetries of nature and physics beyond the Standard Model…

Charge Radii Measurements of Exotic Tin Isotopes in the Proximity of and

F. P. Gustafsson, L. V. Rodríguez, R. F. Garcia Ruiz +51

We report nuclear charge radii for the isotopes Sn, measured using two different collinear laser spectroscopy techniques at ISOLDE-CERN. These measurements clarify the…

Reduction in nuclear size and quadrupole deformation of high-spin isomers of 127,129In

A. R. Vernon, C. L. Binnersley, R. F. Garcia Ruiz +29

We employed laser spectroscopy of atomic transitions to measure the nuclear charge radii and electromagnetic properties of the high-spin isomeric states in neutron-rich indium isot…

Improving the predictive power of empirical shell-model Hamiltonians

J. A. Purcell, B. A. Brown, B. C. He +2

We present two developments which enhance the predictive power of empirical shell-model Hamiltonians for cases in which calibration data are sparse. A recent improvement in the ab…

Improved structure of calcium isotopes from ab initio calculations

M. Heinz, T. Miyagi, S. R. Stroberg +3

The in-medium similarity renormalization group (IMSRG) is a powerful and flexible many-body method to compute the structure of nuclei starting from nuclear forces. Recent developme…

Spurious Isospin Breaking in the In-medium Similarity Renormalization Group

A. Farren, S. R. Stroberg

Robustly quantifying the uncertainty in the isospin-related theoretical correction to superallowed beta decay rates is vital for a correct assessment of CKM unitarity. To th…
