Its melting point is 28.7 C, and it boils at 690 C. The electronic configuration of Cesium is (Xe)(6s 1). Its atomic radius is 0.267 nm. At room temperature Cesium has a body-centered cubic crystal ...

The definition of the hyperfine transitions of cesium was — by international agreement — 9,192,631,770 Hz. A 5 MHz crystal oscillator generates a signal that is modulated by a 137 Hz signal.

Scientists developed a highly accurate optical ion clock, improving time measurement precision by 1,000 times.

The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the ...

The focus of the study was a bulk single crystal of a topological kagome metal ... arranged on a so-called kagome lattice—a pattern of interlaced triangles and hexagons—stacked on top of one another, ...

In an optical atomic clock, atoms are irradiated with laser light. If the laser has exactly the right frequency, the atoms change their quantum mechanical state. All external influences on the atoms ...

Studying such crystals has allowed for advances in the ... alternating lattice of sodium and chlorine that forms table salt; ...
