Thermotransmission measurements have been carried out on thin, self-supported, semitransparent gold films in the 1.8–3.5-eV energy region. The results compare very favorably with the spectra of Rosei et al., taken on quartz-backed samples, showing the feasibility of extending the techniques of modulation spectroscopy into the soft x-ray region. Moreover, it is shown that the widths of the spectral features are a factor of two smaller than those obtained on films evaporated on a quartz substrate. The thermal time constant is in the range of a few milliseconds, so that a very high modulation efficiency can be obtained, even when operating at several hundred hertz.

  10. Before this experiment was performed, it was widely believed that the intrinsic lifetime broadening of the core levels or of high-lying energy levels would completely smear out any structure in modulated spectra in this energy region.
