/ Seidlitz, M (Cologne U.) ; Reiter, P (Cologne U.) ; Altenkirch, R (Cologne U.) ; Bastin, B (KU Leuven, Dept. Phys. Astron.) ; Bauer, C (Darmstadt, Tech. Hochsch.) ; Blazhev, A (Cologne U.) ; Bree, N (KU Leuven, Dept. Phys. Astron.) ; Bruyneel, B (Cologne U.) ; Butler, P A (Liverpool U.) ; Cederkäll, J (Lund U.) et al.
Nuclear shell evolution in neutron-rich Na nuclei around N=20 was studied by determining reduced transition probabilities, i.e., B(E2) and B(M1) values, in order to map the border of the island of inversion. To this end Coulomb-excitation experiments, employing radioactive 29,30Na beams with a final beam energy of 2.85 MeV/nucleon, were performed at REX-ISOLDE, CERN. [...]

Astron. ; SCK-CEN, Mol) ; Fedosseev, V N (CERN) et al.
The structure of low-spin states originating from shape-coexisting configurations in $^{68}_{40}$Ni$_{28}$ was directly probed via the two-neutron transfer reaction $^{66}$Ni$(t,p)^{68}$Ni in inverse kinematics using a radioactive ion beam on a radioactive target. The direct feeding to the first excited 0$^+$ state was measured for center-of-mass angles 4°–16° and amounts to an integral of 4.2(16)% relative to the ground state. [...]

The neutron deficient $^{188–198}$Pb isotopes have been studied in a Coulomb excitation measurement employing the Miniball spectrometer and radioactive beams from REX-ISOLDE, CERN. These isotopes are of particular importance as they lie in a transitional region, where the intruding structures, associated with different deformed shapes, come down in energy close to the spherical ground state.
