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 3<i>d</i><sup>9</sup>-3<i>d</i><sup>8</sup>4<i>p</i> 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 3<i>p</i><sup>6</sup>3<i>d</i><sup>9</sup>-3<i>p</i><sup>5</sup>3<i>d</i><sup>10</sup> transitions in these ions. The previous analysis of Mo Xvi was partially revised and extended.
