1. Atomic nucleus excited with laser: A breakthrough after decades Total comment counts : 31 Summary Physicists have achieved a major breakthrough by exciting the “thorium transition” using lasers. This discovery opens the door to revolutionary high precision technologies, such as nuclear clocks. The thorium transition is a specific state of thorium atomic nuclei that has been sought after by scientists for years. By using a laser to transfer the atomic nuclei into a higher energy state and tracking its return to its original state, researchers can combine quantum physics and nuclear physics....
