Two-body currents at finite momentum transfer and applications to M1 transitions

C. Brase, T. Miyagi, J. Menéndez +1

We explore the impact of two-body currents (2BCs) at finite momentum transfer with a focus on magnetic dipole properties in Ca and Ti. To this end, we derive a multip…

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…

Ab initio computations of the fourth-order charge density moments of Ca and Pb

T. Miyagi, M. Heinz, A. Schwenk

Neutron skins of neutron-rich nuclei connect nuclei with the matter in neutron stars. High-precision measurements of nuclear charge densities to extract higher-order moments are pr…

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…

Electromagnetic Properties of Indium Isotopes Elucidate the Doubly Magic Character of Sn

J. Karthein, C. M. Ricketts, R. F. Garcia Ruiz +24

Our understanding of nuclear properties in the vicinity of Sn, suggested to be the heaviest doubly magic nucleus with equal numbers of protons (Z=50) and neutrons (N=50), h…
