Theoretical study of transition matrix elements in cadmium for vacuum-ultraviolet generation in Th nuclear clock applications
Gleb Penyazkov, Yanmei Yu, Leonid V. Skripnikov +1
The relativistic Fock-space coupled-cluster methods are applied to the cadmium atom. A large number of transition energies and matrix elements are calculated for the $ ^{…

A continuous-wave vacuum ultraviolet laser for the nuclear clock
Qi Xiao, Gleb Penyazkov, Xiangliang Li +14
The exceptionally low-energy isomeric transition in Th at around 148.4 nm offers a unique opportunity for coherent nuclear control and the realisation of a nuclear clock. R…
