First step to the nuclear clock

For the first time, researchers are measuring the energy of a transition in the atomic nucleus of thorium Atomic nuclei of the thorium-229 isotope could enable a whole new kind of ultra-precise clocks. In these nucleus clocks vibrations in the atomic nucleus set the clock. © TU Vienna Read out Breakthrough for Better Timekeeping: Physicists have made an important step towards an atomic nucleus clock - a clock in which oscillations in the nucleus themselves set the pace.
