How big is a cesium atom
WebNote that this frequency occurs when the Cesium-133 atom is in isolation at absolute zero temperature; in reality corrections for this are necessary. Still, the atomic clocks using … WebThe cesium clock is the most accurate type of clock yet developed. This device makes use of transitions between the spin states of the cesium nucleus and produces a frequency which is so regular that it has been adopted for establishing the time standard. Like electrons, many atomic nuclei have spin. The spin of these nuclei produces a set of small …
