1 E-18 s
From Wikipedia, the free encyclopedia
To compare various orders of magnitude of time units, this page lists units of time between 10−18 and 10−15 seconds (i.e. between 1 attosecond and 1 femtosecond). An attosecond is one billionth of one billionth of a second. (One attosecond is to one second what one second is to the age of the universe.) See also times of other orders of magnitude.
The word attosecond originates from the Danish word for eighteen (atten).
- shorter times
- 1 attosecond (1 as) – estimated time it takes for an atomic nucleus to recoil
- about 100 attoseconds – record for shortest time interval measured as of February 2004 (BBC News)
- about 200 attoseconds – half-life of beryllium-8, maximum time available for the triple-alpha process for the synthesis of carbon and heavier elements in stars.
- 250 attoseconds – the shortest pulses of laser light yet created (2002)
- 320 attoseconds – estimated time it takes electrons to hop between atoms
- longer times
