Researchers in Germany and Austria have made progress in developing a nuclear clock based on thorium-229, demonstrating the ability to put nuclei of the isotope into a low-lying metastable state with exceptionally low excitation energy. This advancement could lead to a more stable and practical solid-state nuclear clock, offering potential applications in detecting time variations related to new physics beyond the Standard Model and measuring time dilation due to gravitational differences.
Researchers at CERN's ISOLDE facility have made a key step towards building a nuclear clock based on a periodic transition between two states of an atomic nucleus, specifically the nucleus of an isotope of thorium. Such a clock could be more precise than today's most precise atomic clocks and could serve as a sensitive tool to search for new phenomena beyond the Standard Model. The team produced thorium-229 nuclei in the isomeric state in a novel way and investigated the nuclei using vacuum-ultraviolet spectroscopy, achieving a seven times more precise measurement of the isomer's energy than previous measurements.
Scientists have observed a photon emitted by the nucleus of a thorium isotope, a crucial step in building a nuclear clock that could offer even more precise timekeeping than atomic clocks. The thorium-229 nucleus undergoes a transition with a unique energy and frequency suitable for very precise timekeeping, but observing this transition and identifying its energy precisely are difficult tasks. The detection of the photon emitted in this transition is a significant advance towards the development of nuclear clocks.
