Scientists Develop World's First Working Nuclear Clocks Using Thorium-229
Scientists from Europe and China have developed the world's first working nuclear clocks, using the thorium-229 isotope embedded in calcium fluoride crystals. Unlike atomic clocks that measure electron transitions, these nuclear clocks track energy changes within the atomic nucleus, offering potential for greater precision and stability. The clocks use ultraviolet lasers to excite thorium nuclei, with feedback systems correcting laser frequency drift. While current models do not yet surpass atomic clocks, they represent a significant advance in timekeeping technology with applications in navigation and fundamental physics.
