Abstract

X-ray photoemission studies were performed on the $4 d 5 s 5 p$ elements Pd through Te using monochromatized Al ( $K α$ ) radiation. With increasing atomic number the $4 d$ structure evolves from $d$ bands to spin-orbit—split atomiclike core levels. Structure was observed in the $5 s 5 p$ bands for the first time by this method. The cohesive energy was attributed to the $5 p$ bands in In through Sb. Evidence for both bonding and nonbonding $5 p$ bands was obtained for Te.
