Quadrupole Moments of $^{29}$Mg and $^{33}$Mg
/ Yordanov, Deyan Todorov (Orsay, IPN ; Heidelberg, Max Planck Inst. ; CERN) ; Kowalska, Magdalena (CERN) ; Blaum, Klaus (Heidelberg, Max Planck Inst.) ; De Rydt, Marieke (Leuven U.) ; Flanagan, Kieran T. (Manchester U. ; Leuven U.) ; Himpe, Pieter (Leuven U.) ; Lievens, Peter (Leuven U.) ; Mallion, Stephen (Leuven U.) ; Neugart, Rainer (Heidelberg, Max Planck Inst. ; Mainz U., Inst. Kernchem.) ; Neyens, Gerda (Leuven U.) et al.
The quadrupole moments of 29Mg and 33Mg have been constrained by collinear laser spectroscopy at CERN-ISOLDE. The values are consistent with shell-model predictions, thus supporting the current understanding of light nuclei associated with the "island of inversion"..

A negative magnetic moment of $^{23}$Mg has been determined by collinear laser spectroscopy at CERN-ISOLDE. The absolute value is in agreement with previous measurements by nuclear magnetic resonance while the sign points at high-seniority configurations. [...]

Development of a sensitive setup for laser spectroscopy studies of very exotic calcium isotopes
/ Ruiz, R F Garcia (Leuven U. ; Manchester U.) ; Gorges, C (Darmstadt, Tech. Hochsch.) ; Bissell, M (Manchester U.) ; Blaum, K (Heidelberg, Max Planck Inst.) ; Gins, W (Leuven U.) ; Heylen, H (Leuven U.) ; Koenig, K (Darmstadt, Tech. Hochsch.) ; Kaufmann, S (Darmstadt, Tech.

An experimental setup for sensitive high-resolution measurements of hyperfine structure spectra of exotic calcium isotopes has been developed and commissioned at the COLLAPS beam line at ISOLDE, CERN. The technique is based on the radioactive detection of decaying isotopes after optical pumping and state selective neutralization (ROC) (Vermeeren et al 1992 Phys. [...]

Nuclear moments and charge radii of argon isotopes between the neutron-shell closures N = 20 and N = 28
/ Blaum, K (Mainz U., Inst. Phys. ; CERN) ; Geithner, W (Mainz U., Inst. Phys.) ; Lassen, J (Mainz U., Inst. Phys. ; TRIUMF) ; Lievens, P (Leuven U.) ; Marinova, K (LHEP JINR, Dubna) ; Neugart, R (Mainz U., Inst. Phys.)
We report the measurement of optical isotope shifts for 40–44 Ar relative to 38 Ar from which changes in the mean square nuclear charge radii across the 1 f 7 / 2 neutron shell are deduced. In addition, the hyperfine structure of 41 Ar and 43 Ar yields the spins, magnetic dipole and electric quadrupole moments, in particular the spin I = 5 / 2 for 43 Ar. [...]

We report on the changes in mean square charge radii of unstable neon nuclei relative to the stable (20)Ne, based on the measurement of optical isotope shifts. The studies were carried out using collinear laser spectroscopy on a fast beam of neutral neon atoms. [...]
