Spectra of the copperlike ions Sb<sup>22+</sup> and Te<sup>23+</sup> were observed with a laser-produced plasma and a 10.7-m grazing-incidence spectrograph. Wavelengths, energy levels for all n = 4 and n = 5 configurations, and ionization energies were determined for each ion. For Sb<sup>22+</sup> the 6g levels were also determined. Wavelengths for the 4s–4p resonance lines are compared with recent measurements [J. Opt. Soc. Am. B 8, 1799 (1991)] obtained with a tokamak plasma and with semiempirical values [Phys. Rev, A 44, 148 (1991)] obtained from smoothed corrections to relativistic calculations.
