✦ Synopsis

Synchrotron-excited pho:oemission is used to explore the evolution in the electronic structure of the BaPbl.xBixO3 system as a function of x, using cleaved single crystal and scraped ceramic samples. At the metalto-non-metal transition point, a sharp change in surface reactivity is revealed, with metallic samples being more unstable to atmospheric degradation than semiconducting samples. ARPES data shows enhancements in spectral intensity at the Fermi energy away from the F-point; these are compared with band-structure calculations.

We have measured photoemission spectra of BaPbl-xBixO3 and extracted new information about their electronic structure. O 2p non-bonding states are located around the top of the valence band and possibly form the metallic states at the Fermi levei. O 2p-Bi 6s anti-bonding states are located around 1
