Abstract
Cooperative single-photon excitations of two (K+L) and three (K+L+M) electrons in nickel were studied using x-ray absorption spectroscopy. Each of the edges detected has an energy higher by about 164 3 eV than the sum of those required for exciting the electrons involved independently. The probabilities for the two- and three-electron excitation are found to be 0.25% and 0.08%, respectively, of that for a single K-electron excitation.
