Electric dipole polarizability of Ca

R. W. Fearick, P. von Neumann-Cosel, S. Bacca +14

The electric dipole strength distribution in Ca between 5 and 25 MeV has been determined at RCNP, Osaka, from proton inelastic scattering experiments at very forward angles.…

Normal ordering of three-nucleon interactions for ab initio calculations of heavy nuclei

K. Hebeler, V. Durant, J. Hoppe +4

Three-nucleon (3N) interactions are key for an accurate solution of the nuclear many-body problem. However, fully taking into account 3N forces constitutes a computational challeng…

Nuclear Charge Radii of the Nickel Isotopes Ni

S. Malbrunot-Ettenauer, S. Kaufmann, S. Bacca +38

Collinear laser spectroscopy is performed on the nickel isotopes Ni, using a time-resolved photon counting system. From the measured isotope shifts, nuclear charge rad…

Removing center of mass effects in response function and sum rule calculations based on the harmonic oscillator basis

K. Akdogan, D. Layh, I. Weinberger +3

Response functions are at the heart of any comparison of theory with experiment in studies of the nuclear dynamics with electroweak probes. Calculations performed in the laboratory…

shell closure below calcium: Low-lying structure of Ar

M. L. Cortés, W. Rodriguez, P. Doornenbal +78

Low-lying excited states in the isotope Ar were investigated by in-beam -ray spectroscopy following proton- and neutron-knockout, multi-nucleon removal, and proton…

Charge radius of the short-lived Ni and correlation with the dipole polarizability

S. Kaufmann, J. Simonis, S. Bacca +26

We present the first laser spectroscopic measurement of the neutron-rich nucleus Ni at the \mbox{} subshell closure and extract its nuclear charge radius. Since this i…
