Spectra of the cobaltlike ions Sr xii, Y xiii, Zr xiv, Nb xv, and Mo xvi

Spectra of the cobaltlike ions Sr xii, Y xiii, Zr xiv, Nb xv, and Mo xvi have been observed by means of a low-inductance vacuum spark and a 10.7-m grazing-incidence spectrograph in the region 40–95 A. For Y xiii, Zr xiv, Nb xv, and Mo xvi more than 40 transitions of the type 3d9–3d84p were identified in each ion. For Sr xii about 20 such transitions were identified. The identifications were made with the aid of Hartree–Fock and least-squares parametric calculations. New wavelengths were obtained for the 3p63d9–3p53d10 transitions in these ions. The previous analysis of Mo xvi was partially revised and extended.
