Sentences with phrase «ultrafast electron motions»

To observe ultrafast electron motions in space and time, one needs to measure the position of electrons in the material with a precision of the order of 0.1 nm (0.1 nm = 10 - 10 m), roughly corresponding to the distance between neighboring atoms, and on a sub-100 fs time scale (1 fs = 10 - 15s).

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very bright, and the photons delivered must have sufficiently high energy.

Not exact matches

The method, called ultrafast electron diffraction (UED), could help scientists better understand the role of nuclear motions in light - driven processes that naturally occur on extremely fast timescales.

Using SLAC's instrument for ultrafast electron diffraction, researchers were able to directly see the motions of atomic nuclei in vibrating molecules for the first time.

The door for observing the ultrafast motion of electrons deep inside atoms has been opened.
