    "abstract": "Finite symmetry adaptation techniques are applied to the determination of the\nintensity strength of two-photon transitions for ions with one partly-filled\nshell nl in crystalline environments of symmetry G. We treat the case of intra-\nconfigurational transitions as well as the case of inter-configurational\ntransitions. In both cases, the Wigner-Racah algebra of the chain O(3) \u003e G\nallows to extract the polarization dependence from the intensity. The reported\nresults are valid for any strength of the crystalline field.",
