  • charge radii and ground state structure of Lithium Isotopes experiment and theory reexamined
    Physical Review C, 2011
    Co-Authors: W Nortershauser, T Neff, R Sanchez, I Sick
    Abstract:

    Changes in the nuclear charge radii of Lithium Isotopes were determined using a combination of precise isotope shift measurements and theoretical atomic structure calculations. We discuss the choice of the reference isotope for absolute charge radii determinations in the Lithium isotopic chain and report a new value for the charge radius of {sup 6}Li, based on the analysis of the world scattering data. A summary of the Lithium nuclear charge radii obtained in this way is presented. Additionally, new calculations in fermionic molecular dynamics for the Lithium Isotopes were performed. We summarize the status of the Lithium nuclear charge radii, magnetic dipole and electric quadrupole moments from experimental investigations and compare them to the results of various microscopic and three-body nuclear models.

  • isotope shift measurements of stable and short lived Lithium Isotopes for nuclear charge radii determination
    Physical Review A, 2011
    Co-Authors: W Nortershauser, R Sanchez, G Ewald, B A Bushaw, G W F Drake, J A Behr, P Bricault, J Dilling, M Dombsky, S Gotte
    Abstract:

    Changes in the mean square nuclear charge radii along the Lithium isotopic chain were determined using a combination of precise isotope shift measurements and theoretical atomic structure calculations. Nuclear charge radii of light elements are of high interest due to the appearance of the nuclear halo phenomenon in this region of the nuclear chart. During the past years we have developed a laser spectroscopic approach to determine the charge radii of Lithium Isotopes which combines high sensitivity, speed, and accuracy to measure the extremely small field shift of an 8-ms-lifetime isotope with production rates on the order of only 10 000 atoms/s. The method was applied to all bound Isotopes of Lithium including the two-neutron halo isotope {sup 11}Li at the on-line isotope separators at GSI, Darmstadt, Germany, and at TRIUMF, Vancouver, Canada. We describe the laser spectroscopic method in detail, present updated and improved values from theory and experiment, and discuss the results.

  • first measurement of the nuclear charge radii of short lived Lithium Isotopes
    Hyperfine Interactions, 2006
    Co-Authors: W Nortershauser, R Sanchez, G Ewald, S Gotte, R Kirchner, Jurgen H Kluge, T Kuhl, A Wojtaszek, B A Bushaw, G W F Drake
    Abstract:

    A novel method for the determination of nuclear charge radii of Lithium Isotopes is presented. Precise laser spectroscopic measurements of the isotope shift in the Lithium 2s → 3s transition are combined with highly accurate atomic physics calculation of the mass dependent isotope shift to extract the charge-distribution-sensitive information. This approach has been used to determine the charge radii of 8,9Li for the first time.
