2s^22p^5–2s2p^6 transitions in fluorinelike ions from Zr^31+ to Sn^41+

Abstract
Transitions of the type 2s22p5–2s2p6 have been observed in eight fluorinelike ions from Zr31+ to Sn41+. The spectra were produced by focusing light from the Nd:glass Omega laser at the University of Rochester onto solid targets and photographing the resultant plasmas with a 3-m grazing-incidence spectrograph. The identified transitions are in the region 24–60 Å. The measured wavelengths are in good agreement with wavelengths calculated with the semiempirical formulas of Edlén [ Phys. Scr. 28, 51 ( 1983)]. Wavelengths for the 2s22p5 2P3/22P1/2 magnetic-dipole transitions are given for each ion.
