Starting from the Skyrme interaction together with the density-dependent pairing interaction, we study the g factors for the
excitations of 88, 90Sr and 90, 92Zr. The coupling between one- and two-phonon terms in the wave functions of excited states is taken into account within the finite-rank separable approximation. Using the same set of parameters we describe available experimental data and give the prediction for 90Sr,
in comparison to
in the case of 92Zr.
