/ Müller, P. (Darmstadt, Tech. U.) ; Kaufmann, S. (Darmstadt, Tech. U.) ; Miyagi, T. (Darmstadt, Tech. U. ; Heidelberg, Max Planck Inst. ; Darmstadt, EMMI) ; Billowes, J. (Manchester U.) ; Bissell, M.L. (Manchester U.) ; Blaum, K. (Darmstadt, EMMI) ; Cheal, B. (Liverpool U.) ; Garcia Ruiz, R.F. (CERN) ; Gins, W. (Leuven U.) ; Gorges, C. (Darmstadt, Tech. U.) et al.
The magnetic dipole and the spectroscopic quadrupole moments of the nuclear ground states in the odd-mass nickel isotopes $^{59-67}$Ni have been determined using collinear laser spectroscopy at the CERN-ISOLDE facility. They are compared to ab initio valence-space in-medium similarity renormalization group (VS-IMSRG) calculations including contributions of two-body currents as well as to shell-model calculations.

Isomeric excitation energy for $^{99}$In$^{m}$ from mass spectrometry reveals constant trend next to doubly magic $^{100}$Sn
/ Nies, L. (CERN ; Greifswald U.) ; Atanasov, D. (CERN) ; Athanasakis-Kaklamanakis, M. (CERN ; Leuven U.) ; Au, M. (CERN ; Mainz U.) ; Blaum, K. (Heidelberg, Max Planck Inst.) ; Dobaczewski, J. (Warsaw U.) ; Hu, B.S. (TRIUMF) ; Holt, J.D. (TRIUMF ; McGill U.) ; Karthein, J. (MIT) ; Kulikov, I. (Darmstadt, GSI) et al.
The excitation energy of the 1/2$^-$ isomer in $^{99}$In at ${N=50}$ is measured to be 671(37) keV and the mass uncertainty of the 9/2$^+$ ground state is significantly reduced using the ISOLTRAP mass spectrometer at ISOLDE/CERN. The measurements exploit a major improvement in the resolution of the multi-reflection time-of-flight mass spectrometer. [...]

Al (Oxford U.) et al.
The nature of dark matter and properties of neutrinos are among the most pressing issues in contemporary particle physics. The dual-phase xenon time-projection chamber is the leading technology to cover the available parameter space for Weakly Interacting Massive Particles (WIMPs), while featuring extensive sensitivity to many alternative dark matter candidates.

Mass measurements of $^{99-101}$In challenge ab initio nuclear theory of the nuclide $^{100}$Sn
/ Mougeot, M. (Heidelberg, Max Planck Inst. ; CERN) ; Atanasov, D. (CERN) ; Karthein, J. (Heidelberg, Max Planck Inst. ; CERN) ; Wolf, R.N. (Sydney U.) ; Ascher, P. (CENBG, Gradignan) ; Blaum, K.

$^{100}$Sn is of singular interest for nuclear structure. Its closed-shell proton and neutron configuration exhibit exceptional binding and $^{100}$Sn is the heaviest nucleus comprising protons and neutrons in equal number, a feature that enhances the contribution of the short-range, proton-neutron pairing interaction and strongly influences its decay via the weak interaction.

The strength of the $N$ = 28 magic number in neutron-rich argon isotopes is examined through high-precision mass measurements of $^{46-48}$Ar, performed with the ISOLTRAP mass spectrometer at ISOLDE/CERN. The new mass values are up to 90 times more precise than previous measurements. [...]

Charge radius of the short-lived $^{68}$Ni and correlation with the dipole polarizability

(Darmstadt, Tech. U.) et al.
We present the first laser spectroscopic measurement of the neutron-rich nucleus $^{68}$Ni at the \mbox{$N=40$} subshell closure and extract its nuclear charge radius. Since this is the only short-lived isotope for which the dipole polarizability $\alpha_{\rm D}$ has been measured, the combination of these observables provides a benchmark for nuclear structure theory.
