    Notes: Abstract In a CW laser-atomic beam experiment Stark manifolds in barium originating from the Rydberg states 6s40f 1 F 3, 6s40g 1,3 G 4,3 G 5 and 6s40h 1,3 H 5 have been studied. Accurate quantum defect values for higher orbital angular momentum states (l=6, 7) have been determined. The Stark manifolds are also calculated by diagonalization of the energy matrix in the presence of an external electric field. Good agreement between experiment and calculations is obtained.

    Notes: Abstract High resolution laser-atomic-beam spectroscopy has been applied to study the hyperfine structure of the barium 6sng Rydberg series forn=6−40. The singlet-triplet mixing of the two 6sng J=4 series is deduced through a diagonalisation of the total Hamiltonian. Multichannel Quantum Defect Theory (MQDT) has been used to reproduce both experimental level energies of the 6sng J=3,4 and 5 series and the extracted singlet-triplet mixing. The close-coupling channels of the 6sng Rydberg series turn out to be nearly purejj-coupled channels in contradistinction to lowerl Rydberg series. Furthermore MQDT is used to analyse the observed isotope shifts and peak intensities of the 6sng Rydberg series.
