    "abstract": "The parity-allowed two-photon transitions between the ground state 3A2(T2) of\nthe configuration 3d8 in cubical symmetry and the excited states of the same\nconfiguration are obtained via a simple model. This model is developed in a\nsymmetry adapted framework by using second-order mechanisms and ionic\nwave-functions. It is applied to the recent experimental results obtained by\nMcClure and co-workers for Ni2+ in MgO.",
