Abstract = {{We have measured the resonant inelastic x-ray scattering (RIXS) spectra
   at the Cu L-3 edge in a variety of cuprates. Exploiting a considerably
   improved energy resolution (0.8 eV) we recorded significant dependencies
   on the sample composition and orientation, on the scattering geometry,
   and on the incident photon polarization. The RIXS final states
   correspond to two families of electronic excitations, having local (dd
   excitations) and nonlocal (charge-transfer) character. The dd energy
   splitting can be estimated with a simple crystal field model. The RIXS
   at the L-3 edge demonstrates here a great potential, thanks to the
   resonance strength and to the large 2p spin-orbit splitting.}},
