The nuclei in the mass region A =100 around Sr and Zr show a dramatic change of the nuclear ground-state shape from near spherical for N <=58 to strongly deformed for N> = 60. Theoretical calculations predict the coexistence of slightly oblate and strongly prolate deformed configurations in the transitional region. However, excited rotational structures based on the highly deformed...

The miniball and CD array have been used on Rex Isolde to measure particle gamma-coincidences between inelastically scattered protons and gamma-rays from the first excited state of 17F. This method can be used to infer the significance of the inelastic branch in the 14O(alpha p)17F reaction which is a key reaction in X-ray bursters scenarios. Current analysis of the results from this recent...

We report on a Coulomb excitation experiment at `safe' energies on the even-even neutron-deficient 184,186,188Hg isotopes at the REX-ISOLDE radioactive beam facility. For the first time a Coulomb excitation experiment using post-accelerated radioactive ion beams was performed in the heavy mass region. Apart from the first 2+ to the 0+ ground state transition, also Coulex towards the second 2+...

Two experimental campaigns have been carried out at REX-ISOLDE and MINIBALL in order to determine the magnetic moment of the first excited state in 138Xe with the technique of transient magnetic fields. 138Xe ion beams of 2.9 MeV/u and different multilayered targets were used for Coulomb excitation. De-excitation gamma rays were measured in four MINIBALL cluster detectors in coincidence with...

We aim to elucidate the fundamental chemistry of heavy metal - protein interactions. This involves both studies of model systems, designed proteins and naturally occurring proteins, as well as the interpretation of the spectroscopic data using quantum mechanical calculations. We will present data on model systems (coordination compounds) and proteins recorded recently at ISOLDE.

The perovskite manganites of the family RMnO3 (R=Eu, Gd, Ho, Y, Er and Lu) show different competing orders, e.g. orbital, magnetic, and dielectric, that lead to intriguing properties as colossal magnetoresistance and multiferroic behaviour.
Looking forward to investigate locally the interplay between structural, electric and magnetic degrees of freedom, samples have been synthesized via...

The weakening of the N=28 shell closure for neutron-rich nuclei and the development of deformation and shape coexistence in this mass region were addressed in a low-energy Coulomb excitation experiment using a radioactive 44Ar beam from SPIRAL facility of GANIL. The Ar44 ions were post-accelerated to 2.7 and 3.7 MeV/nucleon and Coulomb excited on 109Ag and 208Pb targets, respectively. The...

The advent of radioactive ion beams (RIBs) places exotic nuclei within reach of experimental study. In particular, RIBs enables a new investigation of the low energy structure of isotopes in the vicinity of the doubly magic 100Sn nucleus. We present here the first results from a series of measurements of the reduced transition probability - the B(E2) value - for the neutron deficient...
