Atom-Billiards with X-Rays: a new Approach to look inside of Molecules

Since these early days of quantum mechanics, it is known that photons also possess momentum. The photon’s ability to transfer momentum was used in a novel approach by scientists of the Max Born Institute, Uppsala University, and the European X-Ray Free-Electron Laser Facility to observe a fundamental process in the interaction of x-rays with atoms. The detailed experimental and theoretical results are reported in the journal Science.
