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 me

✦ Synopsis
The t.eslv;lerature (T) dependences of the critical Josephsoo current I c across a avnmetrical tunnel junctia1 between partially-gapped ~Ca1ductor were calallated. The partial electra1 spectrum dielectrizatia1 is of the spin-singlet type. I c falls rapidly when I..' == Nnd(O)!Nd(O) decreases and ĩncreases.

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
