摘要: The spectrum of Pr3+ produced by a sliding spark discharge was photographed in the wavelength range 800 to 3100 A with 35-ft Eagle vacuum spectrograph. An analysis resulting line list led discovery all levels 4f2 (except 1S0), 4f5d, 4f6s, and 4f6p configurations. interaction parameters for each configuration were derived from least-squares fit energy formulas observed levels.
