Abstract = {{We present experimental and theoretical results on CoO resonant Raman
   scattering (RRS) with excitation at many values in the whole
   Co2+-L-2,L-3, region, and with a final state containing a Co-3 s hole.
   The theory includes the final-state interaction between the
   configurations with one 3 s hole and that with two 3 p holes
   {[}configuration interaction (CI)]. A cluster calculation with CI
   reproduces the experimental results with excitation spanning the whole
   L-3 region. In the L-2 region the theory reproduces the evolution of the
   RRS doublet at higher outgoing energy. On this basis the role of CI and
   of the ligand hole effects are discussed vs the excitation energy. At
   lease 5 eV above the L-3 threshold, the experimental results show also a
   nondispersive component, with the intensity rapidly increasing with the
   excitation energy. The position and shape of this component are well
   reproduced by a model calculation accounting for all possible partitions
   between the transitions to the continuum and to the 3 d shell. However,
   the intensity of the calculated nondispersive component is about an
   order of magnitude smaller than the measured one. The implications of
   this fact in terms of the dynamics of the intermediate state are
   outlined.}},
