Measurements in thorium-229 take a step towards the direct laser excitation of an atomic nucleus in this unique isotope. Nuclear clocks could make our time measurement even more accurate than atomic ...

Nuclear clocks could make our time measurement even more accurate than atomic clocks. The key to this lies in thorium-229, an atomic nucleus whose lowest excited state has very low energy. A research ...
