    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.

    The 5dnd and 5dng J=4, 3 and 2 and 5dns J=2 series in barium: linewidths and linestrengths (1989)
    Springer
    The European physical journal 14 (1989), S. 119-128

    Notes: Abstract The 5dnd and 5dng J=2, 3 and 4 as well as the 5dns J=2 autoionising series of barium have been studied with two-step pulsed laser excitations in an atomic beam. Dipole moments and the interactions with the 6s∈l continua were fitted starting from existing Multi-channel Quantum Defect Theory (MQDT) analyses. The interactions of the 5dnd J=4 and 2, and 5dns J=2 series with 6sεg J=4 and 6sεd J=2 continua could be analysed succesfully.
