A thorium-229 optical nuclear clock with feedback loop
L. Toscani De Col, T. Riebner, I. Morawetz +25
The laser-accessible nuclear transition in the thorium-229 isotope has been identified as a promising candidate for the realization of an optical nuclear clock. Such a nuclear cloc…

Laser spectroscopy on the hyperfine structure and isotope shift of sympathetically cooled Th ions
G. Zitzer, J. Tiedau, Ch. E. Düllmann +2
The hyperfine structure of Th ions in the nuclear ground state is investigated via laser spectroscopy of trapped Th ions that are sympathetically cooled by la…

Laser-Induced Quenching of the Th-229 Nuclear Clock Isomer in Calcium Fluoride
F. Schaden, T. Riebner, I. Morawetz +11
The 10-minute radiative lifetime of the first excited Th nuclear state in ionic crystals provides narrow spectroscopic linewidths, enabling the realization of a soli…
