Towards $^{31}$Mg-$\beta$-NMR resonance linewidths adequate for applications in magnesium chemistry
/ Stachura, M (TRIUMF) ; McFadden, R M L (British Columbia U., Chem. Dept.) ; Chatzichristos, A (British Columbia U.) ; Dehn, M H (British Columbia U.) ; Gottberg, A (TRIUMF) ; Hemmingsen, L (U. Copenhagen (main)) ; Jancso, A (Szeged U.) ; Karner, V L (British Columbia U., Chem. Dept.) ; Kiefl, R F (British Columbia U.) ; Larsen, F H (U. Copenhagen (main)) et al.
The span of most chemical shifts recorded in conventional $^{25}$Mg-NMR spectroscopy is $\sim$ 100 ppm. Accordingly, linewidths of $\sim$ 10 ppm or better are desirable to achieve adequate resolution for applications in chemistry. [...]

/ISOLDE
Laser spectroscopy measurements have been carried out on the very neutron-rich tin isotopes with the COMPLIS experimental setup. Using the 5s 2 5p 2 3 P 0 → 5s 2 5p6s 3 P 1 optical transition, hyperfine spectra of 126–132 Sn and 125 m ,127 m ,129 m –131 m Sn where recorded for the first time. [...]

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. [...]

Phys. Astron.) ; Eliav, E (Tel Aviv U.) ; Fedorov, D V (PNPI, CSTD) ; Fedosseev, V N (CERN) et al.
he radioactive element astatine exists only in trace amounts in nature. Its properties can therefore only be explored by study of the minute quantities of artificially produced isotopes or by performing theoretical calculations. [...]
