Abstract = {{From a spin-resolved photoemission study on the Bi2Sr2CaCu2O8+delta
   superconductor, we show experimentally that the first ionization state
   is of nearly pure singlet character. This is true both above and below
   the superconducting transition and in the presence of doping and band
   formation. This provides direct support for the existence and stability
   of Zhang-Rice singlets in high-temperature superconductors, justifying
   the ansatz of single-band models. Moreover, we establish this technique
   as an important probe for a wide range of cuprates and strongly
   correlated materials.}},
