Measurement of the electric quadrupole moments of $^{26-29}$Na / Keim, M ; Georg, U ; Klein, A ; Neugart, R ; Neuroth, M ; Wilbert, S ; Lievens, P ; Vermeeren, L ; Brown, B A /ISOLDE Collaboration
The nuclear electric quadrupole moments of the isotopes $^{26}$Na, $^{27}$Na, $^{28}$Na and $^{29}$Na were measured by $\beta$-NMR spectroscopy in single crystals of LiNbO$_3$ and NaNO$_3$. High degrees of nuclear polarization were produced by optical pumping of the sodium atoms in a fast beam with a collinear laser beam.The polarized nuclei were implanted into the crystals and NMR signals were observed in the $\beta$-decay asymmetries.

A beam diagnostic system for low-intensity radioactive beams / Kruglov, K ; Weissman, L ; Van den Bergh, P ; Andreyev, A ; Huyse, M ; Van Duppen, P
Modern experiments with secondary radioactive beams create new demands on beam diagnostics which has to provide on-line information on the low-intensity beams. We describe here a beam diagnostics system developed for the REX-ISOLDE facility (CERN), based on the observation of secondary electrons produced by a beam, impinging onto a foil. [...]

Spectroscopy of $^{34,35}Si$ by $\beta$ decay : sd-fp shell gap and single-particle states / ISOLDE Collaboration
The $^{34,35}Al\beta$ decays were studied at the CERN on-line mass separator ISOLDE by $\beta-\gamma, \beta-\gamma-\gamma$ and $\beta-n-\gamma$ measurements, in order to corroborate thelow-level description of $^{34}Si$ and to obtain the first information on the level structure of the N=21 isotope $^{35}Si$. Earlier observed $\gamma$ lines in $^{34} Al$ decay were confirmed and new gamma transitions following both beta decay and $\beta$-delayed neutron emission were established. [...]

First on-line $\beta$-NMR on oriented nuclei : magnetic dipole moments of the $\nu{p}^{-1}_{1/2}; 1/2^-$ ground state in $^{67}$Ni and $\pi{p}^{+1}_{3/2}; 3/2^-$ ground state in $^{69}$Cu / ISOLDE Collaboration
The first fully on-line use of the angular distribution of $\beta$ - emission in detection of NMR of nuclei oriented at low temperatures is reported. The magnetic moments of the single valence particle, intermediate mass, isotopes $^{67}$Ni($\nu{p}^{-1}_{1/2}$; 1/2$^{-}$) and $^{69}$Cu($\pi{p}^{+1}_{ 3/2}$; 3/2$^{-}$) are measured to be +0.601(5)$\mu_{N}$ and +2.84(1)$\mu_{N}$ respectively, revealing only a small deviation from the neutron $p_{1/2}$ single-particle value in the former and a large deviation from the proton $p_{3/2}$ single-particle value in the latter.
