(Laue-Langevin Inst.) et al.
Background: Shell evolution can impact the structure of the nuclei and lead to effects such as shape coexistence. The nuclei around $^{68}$Ni represent an excellent study case, however, spectroscopic information of the neutron-rich, $Z<28$ nuclei is limited. [...]

Shape coexistence studied in ${}^{\mathrm{182,184}}$Hg via the β decay of ${}^{\mathrm{182,184}}$Tl
/ Rapisarda, E (Leuven U. ; PSI, Villigen) ; Andreyev, A N (York U., England) ; Antalic, S (Comenius U.) ; Barzakh, A (St. Petersburg, INP) ; Cocolios, T E (Leuven U.) ; Darby, I G (Leuven U.) ; Groote, R De (Leuven U.) ; De Witte, H (Leuven U.) ; Diriken, J (Leuven U.) ; Elseviers, J (Leuven U.) et al.
The ${\beta }^{+}$/EC decay of ${}^{\mathrm{182,184}}$Tl to excited states in the daughter nuclei ${}^{\mathrm{182,184}}$Hg has been investigated at the CERN on-line isotope mass separator facility. In both Tl nuclei two β-decaying states were observed. [...]

Experimental study of the $^{66}$Ni$(d,p)^{67}$Ni one-neutron transfer reaction
/ Diriken, J. (Leuven U. ; SCK-CEN, Mol) ; Patronis, N. (Ioannina U. ; Leuven U.) ; Andreyev, A.N. (JAERI, Tokai ; York U., England ; Leuven U.) ; Antalic, S. (Comenius U.) ; Bildstein, V. (Munich, Tech. U.) ; Blazhev, A. (U. Cologne) ; Darby, I.G. (Leuven U.) ; De Witte, H. (Leuven U.) ; Eberth, J. (U. Cologne) ; Elseviers, J. (Leuven U.) et al.
The quasi-SU(3) sequence of the positive parity $νg_{9/2}, d_{5/2}, s_{1/2}$ orbitals above the N=40 shell gap are assumed to induce strong quadrupole collectivity in the neutron-rich Fe (Z=26) and Cr (Z=24) isotopes below the nickel region. In this paper the position and strength of these single-particle orbitals are characterized in the neighborhood of $^{68}$Ni (Z=28,N=40) through the $^{66}$Ni($d,p$)$^{67}$Ni one-neutron transfer reaction at 2.95 MeV/nucleon in inverse kinematics, performed at the REX-ISOLDE facility in CERN.

Study of the deformation-driving $\nu d_{5/2}$ orbital in $^{67}_{28}$Ni$_{39}$ using one-neutron transfer reactions
/ Diriken, J. (Leuven U. ; SCK-CEN, Mol) ; Patronis, N. (Ioannina U. ; Leuven U.) ; Andreyev, A.N. (JAERI, Tokai ; York U., England ; Leuven U.) ; Antalic, S. (Comenius U.) ; Bildstein, V.

The $νg_{9/2} , d_{5/2}, s_{1/2}$ orbitals are assumed to be responsible for the swift onset of collectivity observed in the region below $^{68}$Ni. Especially the single-particle energies and strengths of these orbitals are of importance. [...]

Electromagnetic moments of odd- A Po193–203,211 isotopes

Hyperfine splitting parameters have been measured for the neutron-deficient odd-mass polonium isotopes and isomers Po193–203g,m, Po209,211. The measurement was performed at the ISOLDE (CERN) online mass separator using the in-source resonance ionization spectroscopy technique. [...]

Structure of $^{191}$Pb from $\alpha$- and $\beta$-decay spectroscopy

Complementary studies of $^{191}$Pb have been made in the $\beta$- decay of $^{191}$Bi at LISOL (CRC) and in the $\alpha$- decay of $^{195}$Po at ISOLDE (CERN). Fine structures in the $\alpha$- decay of the low-spin and high-spin isomers of $^{195}$Po have been fully resolved. [...]
