- The spectroscopic data mercury (Hg) I and Hg II was analyzed from beam-foil spectroscopy. The wavelength was found to be of course fixed and independent of the light source and recording conditions. It was found that if the calculated branching ratio was correct, then the Hg II was an important constituent of fluorescent light tube plasmas. The wavelength region from 40 to 600 nm in overlapping wavelength regions was covered, depending on the choice of gratings and detectors.

- Fourier transform spectroscopy has proven to be a useful tool when measuring wavelengths and branching fractions. The high spectral resolution makes it possible to extend and improve term analyses of complex spectra. We present an overview of our measurements with the Fourier transform spectrometer at Lund Observatory. Much of our work is motivated by astrophysical problems, and we show an application of some of our measurements related to the age determination of the Galaxy.
