Proton-neutron pairing correlations in the self-conjugate nucleus $^{42}$Sc

Collinear laser spectroscopy of the $N=Z=21$ self-conjugate nucleus $^{42}$Sc has been performed at the JYFL IGISOL IV facility in order to determine the change in nuclear mean-square charge radius between the $I^{\pi}=0^{+}$ ground state and the $I^{\pi}=7^{+}$ isomer via the measurement of the $^{42\mathrm{g},42\mathrm{m}}$Sc isomer shift. New multi-configurational Dirac-Fock calculations for the atomic mass shift and field shift factors have enabled a recalibration of the charge radii of the $^{42-46}$Sc isotopes which were measured previously.

Structural trends in atomic nuclei from laser spectroscopy of tin
/ Yordanov, Deyan T. (Orsay, IPN ; CERN) ; Rodríguez, Liss V. (Orsay, IPN ; Heidelberg, Max Planck Inst.) ; Balabanski, Dimiter L. (ELI-NP, Bucharest) ; Bieroń, Jacek (Jagiellonian U.) ; Bissell, Mark L.

(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 [...]

Fluorescence detection as a new diagnostics tool for electrostatic ion beam traps
/ Lechner, Simon (CERN ; TU Vienna) ; Fischer, Paul (Greifswald U.) ; Heylen, Hanne (CERN) ; Lagaki, Varvara (CERN ; Greifswald U.) ; Maier, Franziska (Linz U.) ; Plattner, Peter (CERN ; Innsbruck U.) ; Rosenbusch, Marco (Greifswald U.) ; Sels, Simon (CERN) ; Wienholtz, Frank (CERN ; Greifswald U.) ; Wolf, Robert N (Greifswald U.) et al.
In the development towards the Multi Ion Reflection Apparatus for Collinear Laser Spectroscopy (MIRACLS), an optical detection region for the observation of fluorescent light is added to an electrostatic ion beam trap (EIBT). In addition to its use for highly sensitive collinear laser spectroscopy, this fluorescence detection is introduced as a diagnostics tool for the study of the ion dynamics inside an EIBT. [...]

First steps in the development of the Multi Ion Reflection Apparatus for Collinear Laser Spectroscopy
/ Sels, Simon Mark C (CERN) ; Fischer, Paul (Ernst Moritz Arndt Universitaet (DE)) ; Heylen, Hanne (CERN) ; Lagaki, Varvara (Ernst Moritz Arndt Universitaet (DE)) ; Lechner, Simon (University of Vienna (AT)) ; Maier, Franziska Maria (Johannes Kepler University (AT)) ; Plattner, Peter (University of Innsbruck (AT)) ; Rosenbusch, Marco (Ernst Moritz Arndt Universitaet (DE)) ; Wienholtz, Frank (Ernst Moritz Arndt Universitaet (DE)) ; Wolf, Robert (Max-Planck-Gesellschaft (DE)) et al.
Collinear laser spectroscopy (CLS) has been combined with the multi-reflection time-of-flight (MR-ToF) technique. To this end, a photodetection system has been implemented at the drift region of a MR-ToF apparatus and a laser beam has been sent along the path of the ions that are stored between the two ion-optical mirrors.
