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…
Frequency reproducibility of solid-state Th-229 nuclear clocks
Tian Ooi, Jack F. Doyle, Chuankun Zhang +5
Solid-state Th nuclear clocks are set to provide new opportunities for precision metrology and fundamental physics. Taking advantage of a nuclear transition's inherent low…
Temperature sensitivity of a Thorium-229 solid-state nuclear clock
Jacob S. Higgins, Tian Ooi, Jack F. Doyle +5
Quantum state-resolved spectroscopy of the low energy thorium-229 nuclear transition was recently achieved. The five allowed transitions within the electric quadrupole structure we…
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…
