Abstract

Spectra of the copperlike ions Ru15+, Rh16+, Pd17+, Ag18+, Cd19+, In20+, and Sn21+ 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.

Because of a tanscription error and a typographical error, several values in this paper were given incorrectly. In Table VI the energy and the effective quantum number of the 4d2D3/2 level should be 1 780 520 cm-1 and 3.6819, respectively. The fine-structure interval of the 4d2D term should be 65 990 cm-1. In Table XIV, the value of n*(calc) for the 5g2G term of Er39+ should be 4.9882.
