Abstract

Atomic spectra of neutral praseodymium (Pr I) have been measured by means of the atomic-beam laser spectroscopy.Hyperfine structures of 34 atomic transitions in the wavelength range from 544 nm to 596 nm were resolved and hyperfine constants A and B were determined for 57 levels.Out of them, 18 transitions were found to be new ones and the energies and the electronic total angular momenta of 11 fine structure levels were determined for the first time.
