| | Tandem Ions May Lead the Way to Better Atomic Clocks
Physicists at the Commerce Department’s National Institute of Standards and Technology (NIST) have used the natural oscillations of two different types of charged atoms, or ions, confined together in a single trap, to produce the "ticks" that may power a future atomic clock. ... |
