Spectra of the copperlike ions Ru<sup>15+</sup>, Rh<sup>16+</sup>, Pd<sup>17+</sup>, Ag<sup>18+</sup>, Cd<sup>19+</sup>, In<sup>20+</sup>, and Sn<sup>21+</sup> were observed with a laser-produced plasma and a 10.7-m grazing-incidence spectrograph. Wavelengths, energy levels, and ionization energies were determined for each of these ions. The wavelengths are compared with relativistic Hartree–Fock calculations.
