/ Costa, A R G (IST, Lisbon (main)) ; Wahl, U (IST, Lisbon (main)) ; Correia, J G (IST, Lisbon (main)) ; David-Bosne, E (IST, Lisbon (main)) ; Amorim, L M (Leuven U.) ; Augustyns, V (Leuven U.) ; Silva, D J (Porto U., Astron. Dept.) ; da Silva, M R (Lisbon U., CFNUL) ; Pereira, L M C (Leuven U.)
/ISOLDE
Using radioactive isotopes produced at the CERN-ISOLDE facility, the lattice location of the implanted transition metal (TM) ions $^56$Mn, $^59$Fe and $^65$Ni in n-type single-crystalline hexagonal 6H-SiC was studied by means of the emission channeling technique. TM probes on carbon coordinated tetrahedral interstitial sites ($T_C$) and on substitutional silicon sites ($S_{Si,h+k}$) were identified. [...]

Ultra sensitive quantification of Hg$^{2+}$ sorption by functionalized nanoparticles using radioactive tracker spectroscopy

/Isolde
We present an ultra sensitive method to quantify the uptake of Hg by dithiocarbamate functionalized magnetic nanoparticles using radioactive tracker spectroscopy. We show a lower limit of detection of about 10 fg L-1, much lower than any other known techniques used to determine the uptake of Hg (about 104 more sensitive), without the need of digesting or processing the sorption agent. [...]

Evidence of tetragonal distortion as the origin of the ferromagnetic ground state in $\gamma$−Fe nanoparticles
/ Augustyns, V (Leuven U.) ; van Stiphout, K (Leuven U.) ; Joly, V (Leuven U.) ; Lima, T A L (Leuven U.) ; Lippertz, G (Leuven U.) ; Trekels, M (Leuven U.) ; Menéndez, E (Leuven U.) ; Kremer, F (Australian Natl. U., Canberra) ; Wahl, U (IST, Lisbon (main)) ; Costa, A R G (IST, Lisbon (main)) et al.
/Isolde
$\gamma$−Fe and related alloys are model systems of the coupling between structure and magnetism in solids. Since different electronic states (with different volumes and magnetic ordering states) are closely spaced in energy, small perturbations can alter which one is the actual ground state. [...]

The nuclear magnetic moment of $^{208}$Bi and its relevance for a test of bound-state strong-field QED

U.) ; Billowes, J (Manchester U.) ; Bissell, M L (Manchester U.) ; Blaum, K (Heidelberg, Max Planck Inst.) ; Garcia Ruiz, R F (Manchester U.) ; Heylen, H (Heidelberg, Max Planck Inst.) ; Malbrunot-Ettenauer, S (CERN) ; Neyens, G (Leuven U.) ; Nörtershäuser, W (Darmstadt, Tech. U.) ; Plunien, G (Dresden, Tech. U., ITP) et al.
The hyperfine structure splitting in the $6p^{3\ 4}S_{3/2} \rightarrow 6p^27s^4P_{1/2}$ transition at 307 nm in atomic $^{208}$Bi was measured with collinear laser spectroscopy at ISOLDE, CERN. The hyperfine A and B factors of both states were determined with an order of magnitude improved accuracy. [...]

(Cologne U.) et al.
/MINIBALL ; HIE-ISOLDE
The first $2^+$ and $3^-$ states of the doubly magic nucleus $^{132}$Sn are populated via safe Coulomb excitation employing the recently commissioned HIE-ISOLDE accelerator at CERN in conjunction with the highly efficient MINIBALL array. The $^{132}$Sn ions are accelerated to an energy of 5.49 MeV/nucleon and impinged on a $^{206}$Pb target. [...]

A new beamline for laser spin-polarization at ISOLDE
/ Gins, W. (Leuven U.) ; Harding, R.D. (CERN ; York U., England) ; Baranowski, M. (Mickiewicz U., Poznan) ; Bissell, M.L. (Manchester U.) ; Garcia Ruiz, R.F. (Leuven U.) ; Kowalska, M.

A beamline dedicated to the production of laser-polarized radioactive beams has been constructed at ISOLDE, CERN. We present here different simulations leading to the design and construction of the setup, as well as technical details of the full setup and examples of the achieved polarizations for several radioisotopes [...]
