The intramolecular flow of charge, energy and nuclear motion is widely encountered in molecular dynamics and underlies chemical reactivity and biological processes 1,2,3. The intramolecular flow may ...

X-rays, a type of electromagnetic radiation with wavelengths from 0.01 to 10 nanometers, pack enough energy to pierce materials and interact with inner-shell electrons. 1 When they hit a sample, ...

A newly developed laser technology has enabled physicists to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of ...

Antimatter lab: the slow positron beam apparatus used by the Tokyo researchers. (Courtesy: Yasuyuki Nagashima/Tokyo University of Science) Strong evidence that positrons can exist in short-lived bound ...
