D. A. Shirley Created 2026-10-18 Updated 2026-11-05
A physical scientist who helped develop X-ray photoelectron spectroscopy. Measuring the energies of electrons emitted after X-ray absorption probes electronic binding and chemical environment. His research extended from laboratory sources to synchrotron radiation, linking improved light sources with more detailed studies of atoms, molecules and solid materials.[ref]
