Ab initio calculations of $^{229}$ Th band-to-band internal conversion rate in $^{229}$ ThO $_{2}$

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 $ℏ ω_{nuc} \approx 8.35$ eV isomeric transition in $^{229}$ ThO $_{2}$ . 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…
