Defect assignment of the clock site in
Daniel A. Rehn, Harry W. T. Morgan, Harris E. Mason +6
The paper reexamines which crystal defect hosts the 229Th nucleus in CaF2, showing that an isolated Th4+ substituting for Ca2+ with two nearby fluoride interstitials best explains…
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 t…
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…
Laser excitation of the Th nuclear isomeric transition in a solid-state host
R. Elwell, Christian Schneider, Justin Jeet +6
LiSrAlF crystals doped with Th are used in a laser-based search for the nuclear isomeric transition. Two spectroscopic features near the nuclear transition energy are o…
