ScienceDaily (Feb. 25, 2008) With the use of a newly developed technology for generating short pulses from intense laser light, scientists in Sweden have managed to capture the electron's motion for the first time. (Credit: Image courtesy of Johan Mauritsson, Lund University)
"It takes about 150 attoseconds for an electron to circle the nucleus of an atom. An attosecond is 10-18 seconds long, or, expressed in another way: an attosecond is related to a second as a second is related to the age of the universe," says Johan Mauritsson, an assistant professor in atomic physics at the Faculty of Engineering, Lund University.
