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…
Ab initio calculations of Th band-to-band internal conversion rate in ThO
Udeshika C. Perera, H. B. Tran Tan, H. W. T. Morgan +3
We present an ab initio calculation of the band-to-band internal-conversion rate of the eV isomeric transition in ThO. Because the nucl…
Magnetic order, magnons, and crystal fields in van der Waals CeSiI
Wolfgang Simeth, Connor A. Occhialini, Michael E. Ziebel +12
We report neutron, X-ray absorption, and resonant X-ray spectroscopy of magnetic excitations in the new heavy-fermion van-der-Waals superconductor CeSiI. We determined effective Ha…
Field-induced magnetic phase transition driven by a ground state level-crossing in CsErSe
Hope Whitelock, Allen O. Scheie, Marissa McMaster +12
We report a comprehensive study of the low-temperature magnetic properties of the insulating rare-earth triangular magnet CsErSe. We uncover a field-induced level crossing at t…
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…
Explaining the extra crystal field mode in ACeX2
Allen O. Scheie, Sabrina J. Li, Stephen D. Wilson +1
A growing list of Ce-based magnets have shown an extra and heretofore unexplained crystal electric field (CEF) mode at high energies. We describe a process whereby an optical phono…
