Nuclei near the closed shells ,=20 and ,=28,as one goes away from the ß-stability line are discussed. The location of the neutron drip line and questions about the stability of nuclides with .≥8 are considered in connection with the weakening or even vanishing of the shell effects at the magic numbers 20 and 28, and the discovery of the new n

,Mg isotopes and the disappearance of magic ,=20 Laser and β-NMR studies,s of neutron-rich .Mg, .Mg, .Mg and .Mg, along with the spins of the two latter. The magnetic moment of .Mg was derived from its hyperfine structure detected in UV fluorescent light, whereas the nuclear magnetic resonance observed in β-decay asymmetry from a polarised ensemble of nuclei gave the mag

Towards a nuclear charge radius determination for beryllium isotopes,these measurements, combined with precise mass shift calculations, it will be possible to extract model-independent nuclear charge radii of .Be and the one-neutron halo .Be with precision better than 3%. Radioactive beryllium isotopes produced at ISOLDE and ionized with a laser ion source will be co

Investigation of the low-lying isomer in 229Th by collinear laser spectroscopy,ulate the inferred low-lying (5.5 eV) isomeric state in .Th. A laser ionization scheme is currently being developed to improve the yield of .Th from the source. The ion source uses a novel electric field configuration for fast and efficient extraction of α-recoils and is able to provide beams of sho
