Atomic clocks are currently our most precise timekeepers. The present record is held by a clock that is accurate to within a single second in 20 billion years. Researchers led by physicist PD Dr. Peter Thirolf and his team at LMU Munich and including scientists and engineers from Johannes Gutenberg University Mainz, the Helmholtz Institute Mainz, and the GSI Helmholtz Center for Heavy Ion Research in Darmstadt have now experimentally identified a long-sought excitation state, a nuclear isomer in an isotope of the element thorium (Th), which could enhance this level of accuracy by a factor of about ten. Their findings are reported in the scientific journal Nature....
