Prize motivation: "for their pioneering investigations concerning deep inelastic scattering of electrons on protons and bound neutrons, which have been of essential importance for the development of the quark model in particle physics."
Prize share: 1/3
Normal matter consists of atoms possessing nuclei of protons and neutrons, surrounded by electrons. In a series of experiments conducted around 1970, Richard Taylor, Jerome Friedman, and Henry Kendall aimed high-energy electrons at protons and neutrons using a large accelerator. They studied how the electrons scattered during the collisions and how protons were sometimes converted into other particles. Their results supported the theory that protons and neutrons are composed of sub-particles, quarks.
