We report on one- and two-neutron transfer reactions to study the single-particle properties of nuclei at the border of the “island of inversion.” The (d, p)- and (t, p)-reactions in inverse kinematics on the neutron-rich isotope 30Mg, delivered as radioactive beam by the REX-ISOLDE facility, have been investigated. The outgoing protons have been detected and identified by a newly built array of Si detectors. The γ-decay of excited states has been detected in coincidence by the MINIBALL array. First results for 31Mg and from the search for the second, spherical, 0+ state in 32Mg are presented. [ABSTRACT FROM AUTHOR]

Two complementary experimental programs have taken place to investigate the origin and evolution of shape coexistence in the light mercury region. Recoil Distance Doppler-shift measurements were performed at the University of Jyväskylä utilizing the Köln plunger device in conjunction with the JUROGAM+RITU+GREAT setup. In addition, Coulomb excitation measurements of 184,186,188Hg were performed at REX-ISOLDE using the MINIBALL Ge-detector array. The results of the lifetime measurements of the yrast states up to Iπ = 10+ in 182Hg are reported. Preliminary analysis of the Coulomb excitation data is also discussed. [ABSTRACT FROM AUTHOR]

The newly built position sensitive Si detectors array of nearly 4π angular coverage which is going to be installed at the REX-ISOLDE facility at CERN is briefly presented. This setup will be combined with the Miniball detectors array, constituting a unique tool for the study of one-nucleon transfer reactions. The experimental study of d(66Ni,p)67Ni reaction will be proposed, as a starting point for a series of experiments aiming to the study of the single particle character of the levels of the odd mass neutron reach unstable Ni isotopes. In this contribution, the feasibility and sensitivity of the experiment is presented. [ABSTRACT FROM AUTHOR]
