Lines occurring as satellites on the long-wavelength side of the 3d/sup 10/--3d/sup 9/4p resonance lines of Ni-like ions have been investigated with a low-inductance vacuum spark and a 10.7-m spectrograph for the elements Y, Zr, Nb, and Mo. The lines are interpreted as 3d/sup 10/4s--3d/sup 9/4s4p and 3d/sup 10/4p--3d/sup 9/4p/sup 2/ transitions in the Cu-like ions Y XI, Zr XII, Nb XIII, and Mo XIV and 3d/sup 10/4s/sup 2/--3d/sup 9/4s/sup 2/4p transitions in the Zn-like ions Y X, Zr XI, Nb XII, and Mo XIII. The spectra of the Cu-like ions were interpreted by generalized least-squares fits for the energy levels of the sequence of four ions. Thirty-nine levels of 3d/sup 9/4s4p were interpreted simultaneously with a root-mean-square deviation of 122 cm/sup -1/; forty-four levels of 3d/sup 9/4p/sup 2/ were interpreted in the same way with a root-mean-square deviation of 20 cm/sup -1/. Line identifications and energy levels were obtained for the 3d/sup 10/7p configuration of the Cu-like ions Y XI--Mo XIV.
