Notizen: Abstract Photoabsorption, photoelectron, and ejected electron spectra of atomic 3d metals and rare earths in the energy range of the strong 3p→3d and 4d→(4fεf) excitations are presented. TheZ-dependence of the strength, shape and decay channels of the giant resonances is discussed. With increasing Z for the 3d metals the 3p→3d resonances change from almost symmetric lines close to the 3p-ionization limits to broad asymmetric profiles centered well below the 3p-ionization threshold. Autoionization leading to the emission of a 3d electron dominates the decay. For lowZ rare earths the 4d→(4fεf) resonances mainly decay via the emission of a 4d electron whereas for higherZ the emission of a 4f electron takes over.
