Investigation into the properties and structure of unstable nuclei far from stability is a key
avenue of research in modern nuclear physics. These efforts are motivated by the continual …

The spectroscopic hyperfine constants for all the alkali atoms are reported. For atoms from
lithium to cesium, only the long lived atomic isotopes are examined. For francium, the …

Over three and a half decades of collinear laser spectroscopy and the COLLAPS setup have
played a major role in the ISOLDE physics programme. Based on a general experimental …

Combining laser spectroscopy in a Versatile Arc Discharge and Laser Ion Source (VADLIS)
with Penning-trap mass spectrometry at the CERN-ISOLDE facility, this work reports on …

We demonstrate that the isotope shift in isotopomers of diatomic molecules, where the
nucleus of one of its constituent atoms is replaced by another isotope, can be expressed as …

In-source resonance ionization spectroscopy of the neutron-rich actinium isotopes Ac 225−
229 has been performed at the ISAC facility in TRIUMF, probing a D 3/2 2→ P 5/2∘ 4 atomic …

The masses of the exotic isotopes Ac 210− 214 and Ra 210− 214 have been measured with
a multireflection time-of-flight mass spectrograph. These isotopes were obtained in flight as …

The CRIS experiment at CERN-ISOLDE is a dedicated laser spectroscopy setup for high-
resolution hyperfine structure measurements of nuclear observables of exotic isotopes …

Isotope shift relative to Bi 209 and hyperfine splitting for Bi 211, 213 have been measured by
in-source laser spectroscopy at the 306.77-nm atomic transition. The pronounced shell effect …

Nuclei are experimentally observed to have charge radii that show remarkably different
trends to those that may be naively expected from liquid drop or droplet behavior. Instead, its …
