A research team led by Frank Stienkemeier and Lukas Bruder from the Institute of Physics at the University of Freiburg observed real-time ultrafast quantum interferences, or oscillation patterns, of electrons in the atomic shells of rare gas atoms. By exciting rare gas atoms with specially prepared laser pulses and then tracking the atoms’ response with a new measurement technique, the scientists were able to observe oscillations occurring within a period of about 150 attoseconds (as).
Various chemical reactions, such as the breaking of bonds in molecules, are triggered by the absorption of light. In the first moment after the absorption, the distribution of the electrons in the atomic shell changes, significantly influencing the…READ MORE
