Abstract = {{Using spin-resolved resonant photoemission we have probed the singlet
   vs. triplet character of the two-hole state in the layered cuprates
   Bi2Sr2CaCu2O8+delta La2-xSrxCuO4 and Sr2CuO2Cl2. The combination of the
   photon circular polarization with the photoelectron spin detection gives
   access to the character of the photoemission final states, which
   correspond to the two-hole configurations localized at a (CuO4) site. In
   particular, the lowest energy state is found to have a very high singlet
   character in all the measured compounds. This can be considered as a
   strong indication of the existence and stability of the so-called
   Zhang-Rice singlets in the layered cuprates. (C) 2002 Elsevier Science
