Time-resolved Fourier transform infrared emission spectra of atomic Xenon: Newly measured Rydberg g-, h- and i-levels

The time -resolved Fourier transform technique was employed to record the spectrum of neutral xenon (Xe I) within a distinct spectral range of 700-14000 cm-1 range. A complete series of up to one hundred scans were carried out and averaged to obtain a satisfactory signal-to-noise ratio with a resolution of 0.02 cm-1, providing a detailed and high -quality representation of the xenon spectra. All existing observations of atomic Xe (1318 lines of which 111 are observed in this work for the first time) were included into the optimization procedure. As a result, we obtain an updated system of Xe I levels.
