Abstract Laser induced fluorescence (LIF) spectroscopy was used for the investigation of structures of 52 spectral lines of Pr I in the wavelength range 561.3 - 613.9 nm. As a source of free Pr atoms a hollow cathode discharge lamp was used. We monitored selected LIF signals appearing when the laser beam excites the hollow cathode plasma. LIF spectra were recorded in the presence of a magnetic field of about 800 G produced by a permanent magnet for two linear polarizations of the exciting laser beam. We have determined for the first time Landé gJ- factors for 71 levels of neutral Pr and reinvestigated data for several other levels.
