Prediction of Nuclear Clock Transitions Frequency Difference between $^{229}$ Th $^{3 +}$ and $^{229}$ Th $^{4 +}$ via \textit{ab-initio} Self-Consistent Field Theory

Ran Si, Chaofan Shi, Nan Xue +4

The $^{229} Th$ isotope is a promising candidate for nuclear clocks, with its transition frequency influenced by electron-induced nuclear frequency shifts. This effect is com…
