Inside a reactor, uranium atoms undergo nuclear fission, a process in which their nuclei split apart and release energy along with additional particles called neutrons.

Their values influence everything from the behavior of atoms and chemical bonds to the nuclear reactions that power stars and produce elements essential for life.

"The great advantage of the new nuclear clock in Vienna is that, if you use atomic nuclei rather than atoms, much higher precision is possible in principle," says Thorsten Schumm.

By carefully controlling the laser's power and beam diameter, the researchers can ionize a narrow region of air, stripping electrons from atoms and molecules to produce plasma.

Elements are defined by the number of protons in their nucleus—all oxygen atoms have eight, and if an atom has six protons, it’s carbon—but the number of neutrons can vary.
