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…
Electric field gradient in accurate quantum chemical calculations
Andrei Derevianko, U. C. Perera, Marek KroÅnicki +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 Mössbau…
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…
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 t…
A spinless crystal for a high-performance solid-state Th nuclear clock
Harry W. T. Morgan, James E. S. Terhune, Ricky Elwell +5
Solid-state Th nuclear clocks require a host material whose band gap is larger than the 8.4 eV nuclear transition energy. As such, excitation of the Th nuclear stat…
