This paper reports laboratory measurements of the spectrum of the most abundant transition Fe ions in the universe. Spectrum of iron of low-lying excited states has been observed in the wavelength range 250-400Â Ã at Chinese Institute of Atomic Energy on the HI-13 tandem accelerator with beams of 130Â MeV. A number of spectral lines have been mainly classified as transitions of magnesium-, sodium-, neon-, fluorine-like ions. A total of 54 lines have been measured. Most of them have been mainly ascribed to 3s3pk-3pk+1, 3s23pk-3s3pk+1, 2p53s-2p53p, 3s3d-3p3d and 2p53p-2p53d resonance transitions. These spectral lines have been identified, among which 21 are new and accurately measured. The analysis of the spectra was based on a comparison with other experimental results and calculated values.
