Resumen
MVV spectra of ph, Pd, and Ag were measured with and without ionization of their L-3 levels. Extra (MMMVV) structure corresponds to the M45M45 --> M45VV transition following the L3M45M45 transition. We interpret the MMMVV structure for Pd as quasiatomic in nature from its similarity to the corresponding Ag spectral shape and from its agreement with atomic calculations. The Pd quasiatomic MMMVV spectrum arises from a two final-state hole bound state in the Pd d band filled by screening of the core holes. These findings represent the first unambiguous observation of the influence of complete screening on spectral features. 86 7 1362 1365
