    Laser spectroscopy measurement of isotope shifts and nuclear moments of short-lived neon isotopes

    Within the scope of a laser spectroscopy study of nuclear structure in the sd shell we are measuring nuclear moments and isotope shifts of neon isotopes. An ultra-sensitive variant of collinear laser spectroscopy...

    Measurement of nuclear moments and radii by collinear laser spectroscopy and by β-NMR spectroscopy

    Experiments using laser spectroscopy and nuclear magnetic resonance techniques have been performed at ISOLDE on the unstable isotopes of several light elements. The results include nuclear ground state spins, ...

    β-NMR in II–VI semiconductors

    β-active probe nuclei are implanted in nominally undoped ZnSe crystals. β-radiation detected nuclear magnetic resonance (β-NMR) studies are described for two different probe nuclei, 8Li and 12B. This way, the imp...

    Accurate isotope shift measurements on short lived neon isotopes

    We report on fast beam collinear laser spectroscopy measurements that demonstrate the feasibility of accurate isotope shift measurements for short lived Ne isotopes including the proton halo candidate 17Ne. Ultra...

    Implanted light dopants in ZnSe

    Spin polarized radioactive 12B, 12N, and 8Li probe nuclei are implanted in nominally undoped ZnSe at stationary concentrations ≤ 1010 cm-3. These light dopants, one donor and two acceptors, are characterized by β...

    Optical polarization of neutron-rich sodium isotopes and β-NMR measurements of quadrupole moments

    The nuclear quadrupole moments of neutron-rich sodium isotopes are being investigated with the help of in-beam polarization by optical pum** in combination withβ-NMR techniques. First measurements have yielded ...

    Hyperfine structure studies in the 6s 6p3P2-level of barium

    The hfs of the3P2 state of the 6s 6p configuration of atomic barium has been determined for137Ba, applying the collinear fast-beam laser spectroscopy. The data fill the last gap in the experimental information on...
