Optical Transmission Enhancement of Ionic Crystals via Superionic Fluoride Transfer: Growing VUV-Transparent Radioactive Crystals
Kjeld Beeks, Tomas Sikorsky, Fabian Schaden +11
The 8 eV first nuclear excited state in Th is a candidate for implementing an nuclear clock. Doping Th into ionic crystals such as CaF is expected to suppress n…
Growth and characterization of thorium-doped calcium fluoride single crystals
Kjeld Beeks, Tomas Sikorsky, Veronika Rosecker +13
We have grown Th:CaF and Th:CaF single crystals for investigations on the VUV laser-accessible first nuclear excited state of Th. To reach high dopi…
Measuring the Th-229 nuclear isomer transition with U-233 doped crystals
Simon Stellmer, Matthias Schreitl, Georgy Kazakov +2
We propose a simple approach to measure the energy of the few-eV isomeric state in Th-229. To this end, U-229 nuclei are doped into VUV-transparent crystals, where they undergo alp…
Prospects for measuring the 229Th isomer energy using a metallic magnetic microcalorimeter
G. A. Kazakov, V. Schauer, J. Schwestka +7
The Thorium-229 isotope features a nuclear isomer state with an extremely low energy. The currently most accepted energy value, 7.8 +- 0.5 eV, was obtained from an indirect measure…
Atomic clock with nuclear transition: current status in TU Wien
G. A. Kazakov, M. Schreitl, G. Winkler +3
The nucleus of 229Thorium presents a unique isomer state of very low energy and long lifetime, current estimates are around 7.8 eV and seconds to hours respectively. This nuclear t…
