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…

A method to detect the VUV photons from cooled Th:CaF crystals
Ming Guan, Michael Bartokos, Kjeld Beeks +13
Thorium-229, with its exceptionally low-energy nuclear excited state, is a key candidate for developing nuclear clocks. Th-doped CaF crystals, benefiting from calcium f…
