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…
An Embedding Cluster Approach for Accurate Electronic Structure Calculations of (229)Th:CaF2
Kamil Nalikowski, Valera Veryazov, Kjeld Beeks +2
Building on recent advances of the embedded cluster approach combined with multiconfigurational theory, this work investigates the electronic states in thorium-doped CaF2 crystals.…
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…
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…
Radiative Decay of the Th Nuclear Clock Isomer in Different Host Materials
S. V. Pineda, P. Chhetri, S. Bara +42
A comparative vacuum ultraviolet spectroscopy study conducted at ISOLDE-CERN of the radiative decay of the Th nuclear clock isomer embedded in different host materials is…
Fine-structure constant sensitivity of the Th-229 nuclear clock transition
Kjeld Beeks, Georgy A. Kazakov, Fabian Schaden +12
State-resolved laser spectroscopy at the 10 precision level recently reported in :2406.18719 determined the fractional change in nuclear quadrupole moment between th…
Frequency ratio of the Th nuclear isomeric transition and the Sr atomic clock
Chuankun Zhang, Tian Ooi, Jacob S. Higgins +9
Optical atomic clocks use electronic energy levels to precisely keep track of time. A clock based on nuclear energy levels promises a next-generation platform for precision…
Controlling Th isomeric state population in a VUV transparent crystal
Takahiro Hiraki, Koichi Okai, Michael Bartokos +27
The radioisotope Th-229 is renowned for its extraordinarily low-energy, long-lived nuclear first-excited state. This isomeric state can be excited by VUV lasers and the transition…
Revisiting the excitation of the low-lying Ta isomer in optical laser-generated plasma
Simone Gargiulo, Ivan Madan, Benoit Truc +5
The excitation of the Ta isomer in the laser-plasma scenario was claimed to have been observed more than two decades ago. However, the reported experimental finding…
