Th Nuclear Spectroscopy in an Opaque Material: Laser-Based Conversion Electron Mössbauer Spectroscopy of ThO
Ricky Elwell, James E. S. Terhune, Christian Schneider +11
Here, we report the first demonstration of laser-induced conversion electron Mössbauer spectroscopy of the Th nuclear isomeric state, which provides the ability to probe th…

Photo-Induced Quenching of the 229Th Isomer in a Solid-State Host
J. E. S. Terhune, R. Elwell, H. B. Tran Tan +5
The population dynamics of the 229Th isomeric state is studied in a solid-state host under laser illumination. A photoquenching process is observed, where off-resonant vacuum-ultra…

Theory of internal conversion of the thorium-229 nuclear isomer in solid-state hosts
H. W. T. Morgan, H. B. Tran Tan, R. Elwell +3
Laser excitation of thorium-229 nuclei in doped wide bandgap crystals has been demonstrated recently, opening the possibility of developing ultrastable solid-state clocks and sensi…
