2s2 2p5-2s2p6 transitions in fluorinelike ions from Zr(31+) to Sn(41+)

Transitions of the type 2s2 2p5-2s2p6 have been observed in eight fluorinelike ions from Zr(31+) to Sn(41+). 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 A. The measured wavelengths are in good agreement with wavelengths calculated with the semiempirical formulas of Edlen (1983). Wavelengths for the 2s2 2p5 2P3/2-2P1/2 magnetic-dipole transitions are given for each ion.
