Intensity of two photon absorption transitions for Ni$^{2+}$ in MGO
J. Sztucki, M. Daoud1, M. Kibler1

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