Cd I isoelectronic sequence: wavelengths and energy levels for Xe VII through Eu XVI

Low-inductance triggered-spark spectra of Xe through Eu were observed with the National Bureau of Standards 10.7-m normal- and grazing-incidence vacuum spectrographs. Transition arrays of the Cd I isoelectronic sequence were identified as well as those of the Pd I and Ag I sequences previously reported. Energy levels and fitted radial integrals were derived. Perturbations that are due to configuration crossings arising from the contraction of the 4f shell were revealed in these analyses. The ground configuration in the Cd I sequence changes from 5s/sup 2/ to 5s4f at Sm XV and to 4f/sup 2/ at Eu XVI.
