/ Wang, S.J. (Peking U., SKLNPT) ; Kanellakopoulos, A. (Leuven U.) ; Yang, X.F. (Peking U., SKLNPT ; Leuven U.) ; Bai, S.W. (Peking U., SKLNPT) ; Billowes, J. (Manchester U.) ; Bissell, M.L. (Manchester U.) ; Blaum, K. (Heidelberg, Max Planck Inst.) ; Cheal, B. (Manchester U.) ; Devlin, C.S. (Manchester U.) ; Garcia Ruiz, R.F. (MIT ; CERN) et al.
Collinear laser spectroscopy measurements were performed on $^{68-74}$Ge isotopes ($Z = 32$) at ISOLDE-CERN, by probing the $4s^2 4p^2 \, ^3\!P_1 \rightarrow 4s^2 4p 5s \, ^3\!P_1^o$ atomic transition (269~nm) of germanium. Nuclear charge radii are determined via the measured isotope shifts, revealing a larger local variation than the neighboring isotopic chains. [...]

Our understanding of nuclear properties in the vicinity of $^{100}$Sn, suggested to be the heaviest doubly magic nucleus with equal numbers of protons (Z=50) and neutrons (N=50), has been a long-standing challenge for experimental and theoretical nuclear physics. Contradictory experimental evidence exists on the role of nuclear collectivity in this region of the nuclear chart. [...]

Molecules containing short-lived, radioactive nuclei are uniquely positioned to enable a wide range of scientific discoveries in the areas of fundamental symmetries, astrophysics, nuclear structure, and chemistry. Recent advances in the ability to create, cool, and control complex molecules down to the quantum level, along with recent and upcoming advances in radioactive species production at several facilities around the world, create a compelling opportunity to coordinate and combine these efforts to bring precision measurement and control to molecules containing extreme nuclei.

Protons and neutrons in the atomic nucleus move in shells analogous to the electronic shell structures of atoms. Nuclear shell structure varies across the nuclear landscape due to changes of the nuclear mean field with the number of neutrons $N$ and protons $Z$. [...]

Charge radii of exotic potassium isotopes challenge nuclear theory and the magic character of $N = 32$
/ Koszorús, Á. (Leuven U.) ; Yang, X.F. (Peking U., SKLNPT) ; Jiang, W.G. (U. Tennessee, Knoxville ; Oak Ridge ; Chalmers U. Tech.) ; Novario, S.J. (U. Tennessee, Knoxville ; Oak Ridge) ; Bai, S.W.

Nuclear charge radii are sensitive probes of different aspects of the nucleon-nucleon interaction and the bulk properties of nuclear matter; thus, they provide a stringent test and challenge for nuclear theory. The calcium region has been of particular interest, as experimental evidence has suggested a new magic number at $N = 32$ [1-3], while the unexpectedly large increases in the charge radii [4,5] open new questions about the evolution of nuclear size in neutron-rich systems.

Structural trends in atomic nuclei from laser spectroscopy of tin

(CERN ; MIT) et al.
Tin is the chemical element with the largest number of stable isotopes. Its complete proton shell, comparable with the closed electron shells in the chemically inert noble gases, is not a mere precursor to extended stability; since the protons carry the nuclear charge, their spatial arrangement also drives the nuclear electromagnetism [...]
