Right now, the "atomic unit of time" is 24 attoseconds, which is the time it takes an electron to travel from one side of a hydrogen atom to the other. ❋ Daemonwise (2009)
There are as many of these "attoseconds" in one second as there are seconds in the history of the universe. ❋ Unknown (2009)
Researchers have found a way to generate the shortest-ever flash of light – 80 attoseconds (billionths of a billionth of a second) long. ❋ Unknown (2009)
Those laser pulses are only 2.5 femtoseconds (that's billionths of a millionth of a second) long, and the light that flashes off of the neon was calculated at 80 attoseconds (that's billionths of a billionth of a second) long. ❋ Daemonwise (2009)
The results proved that a single electron could escape during a half-wave of the infrared laser, fleeing in less than 400 attoseconds – an unimaginably short time. ❋ Unknown (2007)
The events he probes last for about 100 attoseconds, or 100 quintillionths of a second. ❋ William Harryman (2007)
There is a temporal realm called the Planck scale, where even attoseconds drag by like eons. ❋ William Harryman (2007)
For a little perspective, 100 attoseconds is to one second as a second is to 300 million years. ❋ William Harryman (2007)
The physicists have concluded from this that electrons which a laser pulse knock out of an atom are catapulted from the particle with a delay of several tens of attoseconds. ❋ Unknown (2010)
AS-1: The AS-1 beam line at the Max Planck Institute for Quantum Optics in Garching, Germany, holds the record for the shortest-ever laser pulse: 80 attoseconds, or ❋ Science News (2010)
In the case of the electrons which the team of physicists focused on, the result was a difference of around 20 attoseconds. ❋ Unknown (2010)
They then probed the evolution of this ionization using ultraviolet pulses, each lasting around 100 attoseconds, which they directed along the same path through the krypton. ❋ Unknown (2010)
Their measurements revealed that electrons from different atomic orbitals, although excited simultaneously, leave the atom with a small but measurable time delay of about twenty attoseconds. ❋ Unknown (2010)
However, tracking the motion of valence electrons, the outermost electrons in an atom and those that affect an atom's chemical properties, requires taking snapshots over even shorter periods of time - of the order of attoseconds, or 10 ❋ Unknown (2010)
The atoms were simultaneously hit by extreme ultraviolet pulses with a duration of 180 attoseconds, liberating electrons from their atomic orbitals. ❋ Unknown (2010)
They found that electrons from different atomic orbitals, although excited simultaneously, leave the atom with a small but measurable time delay of about twenty attoseconds. ❋ Unknown (2010)
They now chase the pulse of very energetic ultraviolet light onto the atoms, a pulse which flashes for only a few tens of attoseconds and knocks different electrons out of the noble gas particle. ❋ Unknown (2010)
Accordingly, it takes a few tens of attoseconds before an electron flies out of the atom. ❋ Unknown (2010)
