Direct detection of the 229Th nuclear clock transition
Today’s most precise time and frequency measurements are performed with optical atomic clocks. However, it has been proposed that they could potentially be outperformed by a nuclear clock, which… Expand
On the Stability and Volatility of Group 8 Tetroxides, MO4 (M = Ruthenium, Osmium, and Hassium (Z = 108))
Recently, an experiment to chemically characterize for the first time a compound of the transactinide element hassium (Hs, Z = 108) has been performed. On the basis of the assumption that Hs will b...
Atom-at-a-time laser resonance ionization spectroscopy of nobelium
Optical spectroscopy of a primordial isotope has traditionally formed the basis for understanding the atomic structure of an element. Such studies have been conducted for most elements and… Expand
Superheavy elements at GSI: a broad research program with element 114 in the focus of physics and chemistry

Catching, trapping and in-situ-identification of thorium ions inside Coulomb crystals of 40Ca+ ions
Thorium ions exhibit unique nuclear properties with high relevance for testing symmetries of nature, and Paul traps feature an ideal experimental platform for performing high precision quantum logic… Expand
Energy of the 229Th nuclear clock transition
Owing to its low excitation energy and long radiative lifetime, the first excited isomeric state of thorium-229, 229mTh, can be optically controlled by a laser1,2 and is an ideal candidate for the… Expand
Laser spectroscopic characterization of the nuclear-clock isomer 229mTh
The isotope 229Th is the only nucleus known to possess an excited state 229mTh in the energy range of a few electronvolts—a transition energy typical for electrons in the valence shell of atoms, but… Expand
