Abstract
Extensive new data on perturbed and unperturbed levels of the 6s n s 1 S 0 and 6s n s 3 S 1 Rydberg series of Barium have been obtained in a high-resolution laser atomic-beam experiment. Special attention has been paid to the region aboven=15 where the3 S 1 series is strongly perturbed. The results on hyperfine energies and isotopic field shift ratios are compared with calculations using wavefunctions obtained from a Multi Channel Quantum Defect analysis. The applicability of various approximations to these wavefunctions is discussed. Good agreement between experiment and calculation is obtained.
