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 nucle…
Electric field gradient in accurate quantum chemical calculations
Andrei Derevianko, U. C. Perera, Marek Krośnicki +3
The electric field gradients (EFGs) at the (non-spherical) nucleus contribute to atomic and molecular hyperfine structure and govern Nuclear Quadrupole Resonance (NQR) and Mössbaue…
Nuclear Physics Confronts Relativistic Collisions Of Isobars
Giuliano Giacalone, Jiangyong Jia, Vittorio Somà +43
High-energy collisions involving the isobars Zr and Ru have been performed in 2018 at Brookhaven National Laboratory's Relativistic Heavy Ion Collider (RHIC) a…
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…
Host-dependent frequency offsets in Th nuclear clockwork
U. C. Perera, H. W. T. Morgan, Eric R. Hudson +1
Recent advances in laser excitation of the low-energy nuclear isomer transition in Th have opened avenues for developing nuclear clocks, a novel quantum technology with exc…
Investigation into thorium sulfate as a spinless crystal for a high-performance solid-state nuclear clock
Harry W. T. Morgan, James E. S. Terhune, Albert Bao +9
The isotope has a laser-accessible nuclear transition allowing the construction of a solid-state nuclear clock. Solid-state nuclear clock development has focu…
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…
229Th-doped nonlinear optical crystals for compact solid-state clocks
H. W. T. Morgan, R. Elwell, J. E. S. Terhune +5
The recent laser excitation of the 229Th isomeric transition in a solid-state host opens the door for a portable solid-state nuclear optical clock. However, at present the vacuum-u…
Bubble nuclei: single-particle versus Coulomb interaction effects
U. C. Perera, A. V. Afanasjev
The detailed investigation of microscopic mechanisms leading to the formation of bubble structures in the nuclei has been performed in the framework of covariant density functional…
Charge radii, moments and masses of mercury isotopes across the N = 126 shell closure
T. Day Goodacre, A. V. Afanasjev, A. E. Barzakh +48
Combining laser spectroscopy in a Versatile Arc Discharge and Laser Ion Source, with Penning-trap mass spectrometry at the CERN-ISOLDE facility, this work reports on mean-square ch…
Global performance of covariant density functional theory in description of charge radii and related indicators
A. V. Afanasjev, U. C. Perera, P. Ring
A short review of existing efforts to understand charge radii and related indicators on a global scale within the covariant density functional theory (CDFT) is presented. Using maj…
Charge radii in covariant density functional theory: a global view
U. C. Perera, A. V. Afanasjev, P. Ring
A systematic global investigation of differential charge radii has been performed within the CDFT framework for the first time. Theoretical results obtained with conventional covar…
