Abstract
We report the first observation of hyperfine structure and isotope shift in autoionizing states. This structure was investigated in the 5d32nf J=4,5 (n=36-40) barium Rydberg series, excited from the recently localized metastable 5d2G41 level. An isotope-selective detection method was used in a cw laser spectroscopic experiment on a collimated atomic beam. The experimental data provide valuable additional information for the analyses of these doubly excited series. © 1988 The American Physical Society.
