Continuous-wave laser absorption spectroscopy of the Thorium-229 nucleus
I. Morawetz, T. Riebner, L. Toscani De Col +17
A low-energy nuclear transition in the isotope thorium-229 has been excited in thorium-doped crystals with laser light. This opens the perspective towards a highly stable and robus…
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 Mössbauer spectroscopy of ^{229}Th
Takahiro Hiraki, Takahiko Masuda, Sayuri Takatori +24
Mössbauer spectroscopy is widely used in biochemistry, geology, and solid-state physics to obtain structural information on materials. Here, we extend this technique into the optic…
X-ray-induced quenching of the Th clock isomer in CaF
Ming Guan, Michael Bartokos, Kjeld Beeks +27
Thorium-229 has the lowest nuclear-excited state (an isomer state) at approximately 8.356 eV, making it excitable with tabletop vacuum-ultraviolet lasers. Despite the recent succes…
Density Functional Theory Study of Th-doped LiCAF and LiSAF for Nuclear Clock Applications
Martin Pimon, Tobias Kirschbaum, Thorsten Schumm +2
Thorium-doped LiCaAlF and LiSrAlF (Th:LiCAF and Th:LiSAF) are promising crystals for a solid-state nuclear clock based on the 8 eV transition in Th; however, their…
Electronic Bridge processes in Th-doped LiCAF and LiSAF
Tobias Kirschbaum, Martin Pimon, Andreas Grüneis +2
Electronic bridge mechanisms driving the Th nuclear clock transition in the vacuum-ultraviolet-transparent crystals Th:LiCAF (LiCaAlF) and Th:LiSAF (LiS…
