ATTOSECOND PHYSICS HAS ARRIVED. An Austria-
Canada-Germany collaboration (Ferenc Krausz, Vienna Institute
of Technology, 011-43-1-58801-38711,
ferenc.krausz@tuwien.ac.at) reports that it has produced and
detected, for the first time, isolated x-ray pulses lasting on the
scale of attoseconds, where one attosecond is a billionth of a
billionth of a second (10^-18 s). The reported pulses, lasting
approximately 650 attoseconds (as) and residing in the soft x-ray
part of the electromagnetic spectrum, subsequently provided
attosecond-scale measurements of a physical phenomenon
(specifically, the detachment of an electron from an atom by an
x-ray photon).
