Abstract

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 Å. 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.
