  1. 7. The Many Faces of Laser Spectroscopy at ISOLDE: Probing the Nuclear Structure of Exotic Be, Mg, Cu and Ga Isotopes
    Dr Deyan Yordanov (Max-Planck-Institut für Kernphysik)
    19/11/2008, 14:15
    The most recent highlights from collinear laser-spectroscopy at ISOLDE-CERN will be presented, including the charge-radius of the one-neutron halo 11Be as well as the spins and moments of 21Mg and of 71-75Cu. Specialized techniques have been used in each of these cases to further extend the reach of collinear laser spectroscopy to the extremes. Absolute frequency determinations with a...

  2. 3. Spins and moments of cooled and bunched neutron-rich Ga isotopes: First results using the ISCOOL-COLLAPS apparatus
    Mr Mane Ernesto (University of Manchester)
    19/11/2008, 14:45
    The need for increasing the sensitivity of collinear laser spectroscopy has motivated the development of ion beam manipulation techniques. The ISOLDE ion beam cooler-buncher (ISCOOL) is well suited for this purpose. It has recently been installed at the focal plane of the high resolution separator magnets and is able to reduce the beam emittance by an order of magnitude, as well as release the...

  3. 9. Technical Developments for Precision Spectroscopy of light Isotopes in Collinear Laser Spectroscopy (IS449)
    Christopher Geppert (Gesellschaft fuer Schwerionenforschung mbH (GSI), Darmstadt, Germany)
    19/11/2008, 15:05
    The aim of proposal IS449 is the determination of charge radii of the beryllium isotopic chain 7,9,10,11Be. For a precise extraction of charge radii, a precision of laser spectroscopy on the order of 1 MHz is needed. We have now used for the first time collinear laser spectroscopy to measure the isotope shift of radioactive isotopes to the accuracy required to extract charge radii by...

  4. 13. Results from Transfer Experiments in the Island of Inversion
    Mr Vinzenz Bildstein (Physik-Department E12, TU München)
    19/11/2008, 15:25
    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...

  5. 26. Biological Applications of Perturbed Angular Correlations of γ-Ray Spectroscopy
    Monika Stachura (University of Copenhagen)
    19/11/2008, 15:45
    Perturbed angular correlation of γ-rays (PAC) spectroscopy is a techinque routinely used in solid state physics, however, it has also proved to be a method that allows for studies of biological problems, such as local structure at metal ion binding sites, dynamics of protein folding or protein–protein interactions [1]. In this work we illustrate that PAC spectroscopy is a suitable tool to...

  6. 37. A study of the 1+n+ scenario with the Phoenix booster at ISOLDE
    Ms Melanie Marie-Jeanne (CERN)
    19/11/2008, 16:05
    At ISOLDE / CERN, an on-line test bench is dedicated to charge breeding experiments with a 14 GHz Phoenix ECRIS. The investigation of the 1+-->n+ scenario with exotic ion beams provides useful information for the design of the next generation of radioactive ion beam post-accelerators. The program of tests for the on-line performances was concluded this year. Possibilities of beam purification...
