Abstract
High resolution VUV spectroscopy ({lambda}/{Delta}{lambda} {approx_equal} 10{sup 5}) of Ytterbium I is performed using synchrotron radiation in combination with a 3m spectrograph and a newly developed VUV laser system in combination with a thermionic diode detector offering good linearity. The VUV laser is based on a resonantly enhanced sum-difference scheme in Krypton and provides the most intense tunable VUV light source (bandwidth 6 GHz) available at present. The principal and intercombination series (n=12 to 70) are studied and their relative intensities are given, revealing the strong influence of perturbers. The Zeeman effect in a field of 5.7 Tesla is exploited to extract g-factors. Numerous Rydberg series in the autoionising range (1330 - 1430 A) converging to the {sup 2}F{sub 7/2}, {sup 2}D{sub 3/2} and {sup 2}D{sub 5/2} limits are investigated. Multiple q-reversals can be observed. Lu-Fano-Plots and a K-Matrix approach are used to disentangle the strong interactions between the one-electron inner shell excitations of the closed 4f{sup 14} subshell and the doubly excited valence shell.
