hence be possible to directly excite the atomic nucleus with UV (laser)
radiation, creating a bridge between atomic and nuclear physics. The (expected)
narrow line width of the transition and the intrinsic robustness of nuclear
transitions to external fields makes it a promising candidate for a new
frequency standard. In this presentation
we will review the current state of knowledge on the low-energy nuclear
transition in Thorium-229 and the ongoing quest to measure it’s exact energy.
