Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom.

Scientists have demonstrated that atoms can exhibit wave-like behavior, challenging long-held assumptions that experiments of this nature were impossible and opening new doors in quantum physics. The ...

(Nanowerk News) Turning up the intensity of x-ray beams used to probe the atomic structures of materials can actually reduce the intensity of x-rays scattered from the material, a RIKEN-led team has ...

When a sample fluoresces during a powder x-ray diffraction (XRD) experiment, the resulting errors in the quantitative results may render the experiment meaningless. Fluorescence is especially common ...
