Shielded inner-shell transitions in atomic samarium for tests of fundamental physics
R. Aramyan, D. Budker, V. A. Dzuba +5
Forbidden atomic transitions provide some of the most stringent low-energy tests of physics beyond the Standard Model, with sensitivity set by the interplay between the sought-for…

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…

Sympathetic cooling of trapped Th3+ alpha-recoil ions for laser spectroscopy
G. Zitzer, J. Tiedau, M. V. Okhapkin +5
Sympathetic cooling of Th ions is demonstrated in an experiment where Th and Th are extracted from uranium recoil ion sources and are confined in a linear Pa…
