When the American physicist Arthur Compton discovered that light waves behave like particles in 1922, and could knock electrons out of atoms during an impact experiment, it was a milestone for quantum ...

Researchers from Skoltech, MEPhI, and the Dukhov All-Russian Research Institute of Automation have proposed a new method to create compact gamma-ray sources that are simultaneously brighter, sharper, ...

Particle physicists in the US have gained new insights into what happens when a high-energy photon scatters inelastically off a proton. According to perturbative quantum chromodynamics, the momentum ...

An international team of researchers has developed a new high-resolution x-ray Compton scattering method to visualize the perturbation of redox orbitals in energy-storage materials. The new ...

NASA’s IXPE mission has taken a major leap in solving the mystery behind X-ray emissions from blazar BL Lacertae, a type of supermassive black hole shooting energetic jets toward Earth. By studying ...

Light can be used to knock electrons out of atoms, with light particles and electrons bouncing off each other like two billiard balls - Compton scattering. Why electrons can even be ejected from an ...
