For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the ...
The emission of photons by excited nuclei has been explored for timekeeping and sensing, but nuclear processes that eject electrons offer practical advantages. Electrons in atoms can exist only in ...
