Revolutionary Scandium-based Atomic Clocks Ensure Unprecedented Precision for Eons

Scientists have identified scandium as a promising element for the development of nuclear clocks, which could offer accuracy up to 1 second in 300 billion years. Unlike atomic clocks that rely on electron shell oscillation, nuclear clocks use the oscillation of the atomic nucleus for enhanced timekeeping. Scandium's atomic resonances are more acute than those of electrons, making it a potential candidate. However, generating the necessary oscillation in scandium requires X-rays with high energy levels. The researchers demonstrated a resonant width of only 1.4 femtoelectronvolts, suggesting an accuracy of 1:10,000,000,000,000. This advancement could have applications in extreme metrology, nuclear clock technology, and ultra-high-precision spectroscopy.
