Cooper Minima in the Photoemission Spectra of Solids



S Molodtsov, S Halilov, V Servedio, W Schneider, S Danzenbaecher, J Hinarejos, M Richter, C Laubschat


Variations of the photoionization cross-section of valence states as a function of interatomic distance are studied by means of atomic and solid-state density functional approaches and compared with photoemission data. In contrast to the free atom case, a series of Cooper minima is found for 4d, 5d, and 5f states in Pd, Ag, Au, and U metals. The discovered fundamental phenomenon is of high importance for the correct interpretation of photoemission data.
