    "abstract": "The double-dipole strength distribution in $^{40}$Ca is calculated\nmicroscopically within a model space of 1p1h - and 2p2h excitations. Anharmonic\neffects in the centroid energies of the $0^+$- and $2^+$ components are found\nto be small, in agreement with experimental observation. Firm conclusions about\nthe spreading width cannot be drawn, as yet, due to computational limitations\nin the number of 2p2h states.",
