attosecond

• Eine Zeiteinheit, die einem Trillionstel (10⁻¹⁸) einer Sekunde bzw. einem Tausendstel einer Femtosekunde entspricht und vor allem in der Physik und Chemie zur Messung extrem kurzer Zeiträume verwendet wird.

A unit of time equal to one quintillionth (10⁻¹⁸) of a second, or one thousandth of a femtosecond, used primarily in physics and chemistry to measure extremely short durations.

   One quintillionth (10⁻¹⁸) of a second, or one thousandth of a femtosecond. Used in physics to measure the time it takes for light to travel across a molecule or for electrons to move between atoms.

   Extrem kurze Zeiteinheit

   • An attosecond is so brief that light travels only a few nanometers in that time.
   • Scientists use attosecond lasers to observe electron motion in real time.
   • The attosecond pulse allowed researchers to capture the fastest processes in nature.
