A summary of the advances at the REX-ISOLDE facility during 2007 will be given. In total 3 new elements and 8 new isotopes were delivered for physics, coming either as atomic ions or molecular ions from ISOLDE. The REX-ISOLDE post accelerator has this year also seriously entered the arena of heavy ion beams by accelerating light Hg isotopes to full linac energy. The potential and constraints...

Thirty years after the discovery of the ``island of inversion'' [1] the borders of the island are still not well determined and in particular the evolution of the single-particle structure is not well investigated.
Transfer reactions yield important spectroscopic information, i.e. spin and parity assignments as well as spectroscopic factors, complementary to the information obtained in...

The krypton isotopes are located roughly in the middle of the Z=28 and Z=50 shell closures, where competition of various structures and shapes at low-excitation energy occurs. For example, this can be seen in the case of Z=40 Zirconium Isotopes. In 96Zr (N=56) a strong shell closure was found, interpreted to be reinforced by the Z=40 shell gap. Such a shell gap should quickly disappear moving...

The 1789~keV level in 30Mg was unambiguously identified as the second
excited 0+ state by measuring its E0 transition to the ground state via
conversion electron spectroscopy. This
level corresponds to the strongly deformed intruder 0+ state, thus proving
for the first time shape coexistence in this nucleus at the borderline of the
'Island of Inversion' around N ~20. The matrix...

Measurements of nuclear magnetic moments are of current interest at RIB facilities, because they provide key information about the states of interest, e.g. about their wave functions.
A basic requirement for the measurement of magnetic moments is the existence of an initially spin-aligned nuclear ensemble. We report here that transfer reactions are applicable for such studies. As the...

The first safe Coulomb excitation measurements of 30Mg and 32Mg at safe energies with REX-ISOLDE and MINIBALL clearly confirms the transition in the neutron-rich magnesium isotopes from normal to intruder-dominated configurations between these two Mg isotopes by measuring the B(E2;
0gs+-21+) values of the even-even nuclei. A recent Coulomb excitation
experiment with a post-accelerated odd...
