/ 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 59−67Ni 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.

/ 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 68−74Ge isotopes (Z=32) at ISOLDE-CERN, by probing the 4s24p23P1→4s24p5s3Po1 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. [...]

(CERN ; Heidelberg, Max Planck Inst.) et al.
Nuclear moments of the antimony isotopes 113−133Sb are measured by collinear laser spectroscopy and used to benchmark phenomenological shell-model and \textit{ab initio} calculations in the valence-space in-medium similarity renormalization group (VS-IMSRG). The shell-model calculations reproduce the electromagnetic moments over all Sb isotopes when suitable effective g-factors and charges are employed. [...]

Collinear laser spectroscopy was performed on the isomer of the aluminium isotope 26mAl. The measured isotope shift to 27Al in the 3s23p2P∘3/2→3s24s2S1/2 atomic transition enabled the first experimental determination of the nuclear charge radius of 26mAl, resulting in Rc=\qty{3.130±.015}{\femto\meter}.

The Multi Ion Reflection Apparatus for Collinear Laser Spectroscopy (MIRACLS) seeks to extend the reach of high-resolution collinear laser spectroscopy (CLS) to more exotic radionuclides. In this novel technique, ion bunches of short-lived radioisotopes are trapped between two electrostatic mirrors of a Multi-Reflection Time-of-Flight (MR-ToF) device at 30-keV kinetic energy. [...]

The Multi-Ion Reflection Apparatus for Collinear Laser Spectroscopy
(MIRACLS), currently under development at ISOLDE/CERN, aims to
combine the high resolution of fluorescence-based collinear laser spectroscopy (CLS) with a high sensitivity. This will be achieved by confining
30-keV ion bunches in a Multi-Reflection Time-of-Flight (MR-ToF) device
which allows laser spectroscopic probing for several thousand times. [...]

The electric quadrupole moment of 49Sc was measured by collinear laser spectroscopy at CERN-ISOLDE to be Qs=−0.159(8)eb, and a nearly tenfold improvement in precision was reached for the electromagnetic moments of 47,49Sc. The single-particle behavior and nucleon-nucleon correlations are investigated with the electromagnetic moments of Z=21 isotopes and N=28 isotones as valence neutrons and protons fill the distinctive 0f7/2 orbit, respectively, located between magic numbers, 20 and 28.

An accuracy benchmark of the MIRACLS apparatus: Conventional, single-passage collinear laser spectroscopy inside a MR-ToF device
/ Lagaki, V (CERN ; Greifswald U.) ; Heylen, H (CERN) ; Belosevic, I (TRIUMF) ; Fischer, P (Greifswald U.) ; Kanitz, C (CERN ; Erlangen - Nuremberg U.) ; Lechner, S (CERN ; TU Vienna) ; Maier, F M (CERN ; Greifswald U.) ; Nörtershäuser, W (Darmstadt, Tech.

Collinear laser spectroscopy (CLS) has been performed in a multi-reflection time-of-flight (MR-ToF) device operated in single-pass mode, i.e., without confining the ions in the ion trap. While our Multi Ion Reflection Apparatus for Collinear Laser Spectroscopy (MIRACLS) aims to increase the CLS sensitivity by storing ions in the MR-ToF device, the present work characterises conventional single-passage CLS as a preparatory step for the upcoming comparison with MIRACLS’ multi-pass mode.
