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.

Quadrupole interaction in ternary chalcopyrite semiconductors : experiments and theory
/ Dietrich, M ; Burchard, A ; Degering, D ; Deicher, M ; Kortus, J ; Magerle, R ; Möller, A ; Samokhvalov, V ; Unterricker, S ; Vianden, R
/ISOLDE Collaboration
Electric field gradients have been measured at substitutional lattice sites in ternary semiconductors using perturbed gamma - gamma angular correlation spectroscopy. The experimental results for A/sup I/B/sup III/C/sub 2//sup VI/ chalcopyrite structure compounds and Square Operator A/sup II/B/sub 2//sup III/C/sub 4//sup VI/ defect chalcopyrites are compared with ab-initio calculations.

Identification of Ag-acceptors in $^{111}Ag^{111}Cd$ doped ZnTe and CdTe
/ Hamann, J ; Burchard, A ; Deicher, M ; Filz, T ; Lany, S ; Ostheimer, V ; Strasser, F ; Wolf, H ; Wichert, T
/ISOLDE Collaboration
Nominally undoped ZnTe and CdTe crystals were implanted with radioactive /sup 111/Ag, which decays to /sup 111/Cd, and investigated by photoluminescence spectroscopy (PL). In ZnTe, the PL lines caused by an acceptor level at 121 meV are observed: the principal bound exciton (PBE) line, the donor-acceptor pair (DAP) band, and the two-hole transition lines. [...]

The $\beta$2p -decay mechanism of $^{31}$Ar
/ ISOLDE Collaboration
We have measured the $\beta$-decay of $^{31}$Ar with a high granularity setup sensitive to multiparticle decay branches. Two-proton emission is observed from the isobaric analog state in $^{31}$Cl to the four lowest states in $^{29}$P and furthermore from a large number of states fed in Gamow-Teller transitions. [...]
