A string of experiments using thorium-229 nuclei has brought the long-theorized nuclear clock closer to reality, producing frequency measurements stable enough to challenge the atomic clocks that ...
In 2008, a team of UCLA-led scientists proposed a scheme to use a laser to excite the nucleus of thorium atoms to realize extremely accurate, portable clocks. Last year, they realized this ...

For the first time, an international team of physicists has successfully harnessed a rare orbital transition in atoms of ...
Researchers are looking for new ways to improve timekeeping because even small gains in stability can help physicists discover subtle physical effects. The thorium-229 nuclear clock is a newer venture ...
Last year, a UCLA-led team accomplished something scientists have been trying to do for 50 years. They made radioactive thorium nuclei absorb and emit photons like electrons in an atom do. This ...
