**********************************************
NiO crystal-field :math:`L_{2,3}` XAS & RIXS
**********************************************

The calculation treats NiO as
an ionic Ni :math:`3d^8` site in a cubic field and excites a :math:`2p`
electron into the :math:`3d`. It includes an effective exchange
field acting along the :math:`<112>` direction.

The RIXS spectrum is calculated at the global maximum of the XAS and summed
over two orthogonal outgoing linear polarizations.
