“…Based on the theory of atomic HFS, we wrote an HFS fitting analysis program [39] using a least-squares method called the Simplex method [40]. We performed fitting analysis of the HFS of Pr I spectra by our fitting program.…”

The hyperfine structure patterns of some neutral praseodymium (Pr I) lines in the range of 2969 − 34998 cm−1 were investigated based on the archival data from the Fourier transform spectrometer at the US National Solar Observatory. The hyperfine magnetic dipole interaction constants A are presented by fitting the spectra with our spectral analysis program. The HFS constants A for 56 levels of Pr I from 0.0 to 27602.42 cm−1 were determined.
