“…Shadmi's [23] early systematic treatment of the (4d + 5s) n configurations in the neutral palladium-group atoms was apparently never published and no systematic calculation has been performed for the (4d + 5s) n−1 5p odd-parity configurations in these atoms. Büttgenbach and Jacobs [24] performed a parametric analysis on the fine structure of Zr I and Mo I and determined eigenvector components for some even-parity levels. Wyart [25,26] and Martin and Sugar [27], after examining available data for the odd-parity energy-level structures in Zr, Hf and Rf (which occupy the same column in the periodic table), concluded that more complete and reliable energy-level analyses are needed for a number of 4d-and 5d-shell spectra.…”

The isotope shifts of twelve Zr I 4d35s-4d25s5p transitions in the green and the 4d35s a 5F5-4d35p y 5G6 `reference' transition at 468.78 nm have been determined by the technique of Doppler-free saturated absorption spectroscopy in a sputtered vapour. The specific mass shift (SMS) and the field shift (FS) contributions were separated using a King-plot analysis, in which the SMS of the 468.78 nm reference transition was estimated from ab initio calculations. The 4d35s-4d25s5p transitions, which involve an electron jump 4d→5p, represent an important class in which the SMS is large compared with the FS. This enables SMSs to be determined to high accuracy (1-2%), thus affording stringent tests of ab initio calculations. An interpretation of the isotope shifts was performed using refined multiconfigurational fine-structure calculations and pseudo-relativistic Hartree-Fock (PSUHFR) calculations. The SMS values deduced from the PSUHFR calculations are found to be systematically higher than the experimental SMS values for all levels, by an average factor of 1.45±0.07 (where the uncertainty represents the standard deviation of the distribution). Using PSUHFR estimates for the electron density at the nucleus together with the experimental FS for the 4d35s a 5F5-4d25s5p y 5G6 transition, the 90Zr-92Zr FSs for some relevant odd-parity configurations are predicted to be FS(4d35p) =-419 MHz, FS(4d25s6p) = + 281 MHz and FS(4d5s25p) = + 1012 MHz, relative to the lower-level configuration 4d35s.
