Attosecond

An d' (symbol as) is a unit of time in the International System of Units (SI) equal to 1×10−18 of a second (one quintillionth of a second).<7151606/http://www.memidex.com/attosecond |archive-date=7 April 2019 |url-status=dead }} For comparison, an attosecond is to a second what a second is to about 31.71 billion years. The word "attosecond" is formed by the prefix atto and the unit second. Atto- was derived from the Danish word for eighteen (atten). Its symbol is as. An attosecond is equal to 1000 zeptoseconds, or 1⁄1000 of a femtosecond. Because the next higher SI unit for time is the femtosecond (10−15 seconds), durations of 10−17 s and 10−16 s will typically be expressed as tens or hundreds of attoseconds: Times which can be expressed in attoseconds: * 0.247 attoseconds: travel time of a photon across "the average bond length of molecular hydrogen" * 24 attoseconds: the atomic unit of time * 43 attoseconds: the shortest pulses of laser light yet created * 53 attoseconds: the second-shortest pulses of laser light created * 82 attoseconds (approximately): half-life of beryllium-8, maximum time available for the triple-alpha process for the synthesis of carbon and heavier elements in stars * 84 attoseconds: the approximate half-life of a neutral pion * 100 attoseconds: fastest-ever view of molecular motion * 320 attoseconds: estimated time it takes electrons to transfer between atoms (Wikipedia).
