Electron was the first to take video


26/02/2008

Until recently it has not been possible to obtain clear images of the electron. Its speed is so high that the picture is very blurred. To achieve high-definition images to equipment capable of producing a flash of light, an incredibly short duration.

But now, thanks to technological advances, scientists from Sweden appeared necessary technology for the first time to remove the video motion of the electron. These technologies make it possible to generate short bursts of light (the so-called attosecond pulses) with an intense attosecond laser.

Electron takes about 150 attosecond (attosecond - one quintillion of a second, 10 ^ -18) to make the rotation around the atomic nucleus. But in addition to the shooting of the electron, scientists, with the help of another laser, it was possible to control the direction of the electron motion, allowing capture on collision of an electron from an atom.

Researchers have long promised the world to take pictures or shoot video on the process of electron motion with attosecond laser. And now, when they succeeded, scientists can study the behavior of an electron in its collision with other objects, as well as what happens to the kernel when it leaves the electron (for example, when and how the other electrons fill the void).

Video clip shows the motion of an electron on a wave of light, after it (electron) is knocked out of the atom. Roller length corresponds to a single period of oscillation of the light wave. Then the speed decreases and as processed so that it can be viewed. Today’s news widgets to help you follow the course of the global economy.
