X-ray Laser Measures Leaping Electrons
In an experiment at SLAC's X-ray laser, scientists split molecules into two fragments using pulses of infrared light, and then used X-ray pulses to observe the transfer of electrons.
Image - In this illustration of a severed methyl iodide molecule, electrons jump the gap from one fragment containing carbon and hydrogen atoms (right) to the other fragment, which contains an iodine atom (left).
