摘要：

We have made the first interferomeric measurements of the wavelengths of the important ultraviolet diagnostic lines in the spectra C Iv near 155 nm and Si Iv near 139 nm with a vacuum ultraviolet Fourier transform spectrometer and high-current discharge sources. The wavelength uncertainties were reduced by 1 order of magnitude for the C Iv lines and by 2 orders of magnitude for the Si Iv lines. Our measurements also provide accurate wavelengths for resonance transitions in Al III, Al II, and Si II.
