Precise measurements of beta decays between isobaric analog states of nuclear spin-parity 0+ and isospin T=1 provide important data for testing the electroweak interaction. These so-called superallowed beta decays provide the most precise value of V_ud, the up-down element of the Cabibbo-Kobayashi-Maskawa (CKM) quark-mixing matrix. The most stringent test of the CKM matrix is the top-row...

In-gas cell laser spectroscopy has been developed at the Leuven Isotope Separator On-Line
(LISOL) set-up using heavy- and light-ion induced reactions. The recoiling reaction products are
thermalised in a buffer gas cell filled typically with 300 to 500 mbar of argon. They are
subsequently resonantly photoionized using a two step laser ionization scheme, extracted from
the gas cell,...

The technique of resonant ionization spectroscopy is well known for its selectivity in the production of RIB at ISOL facilities. This feature is now also used for atomic spectroscopy on weakly-produced isotopes (<1 atom/s), otherwise not accessible by conventional laser spectroscopy techniques.
With two protons outside the lead (Z=82) closed core, the polonium isotopes (Z=84) exhibit shape...
