Abstract
Barium spectra emitted from hollow cathode discharges and recorded with Fou rier transform spectrometers in the region 1700-31 000 Angstrom have been u sed for measuring 294 Ba I lines and 52 Ba II lines with uncertainties in t he range +/-0.001 cm(-1) to +/-0.01 cm(-1). Energy level values have been d erived from the measurements. The energy levels have been used for an impro ved determination of the Ba II ionization limit, giving the value 80686.30 +/- 0.10 cm(-1).
