Abstract

Two sets of spin-orbit split Ba 4d core-level photoemission peaks were observed in a crystal of

{YBa}_{2}

{Cu}_{3}

O_{6.9}

. From constant final-state measurements taken as a function of kinetic energy, the low-binding-energy doublet is identified as a surface component. Possible origins of the surface shift are discussed.
