Laser Spectroscopic Investigations of Praseodymium I Transitions: New Energy Levels

[摘要] We report the discovery of about 140 new energy levels of the neutral praseodymium atom, found by means of laser-induced fluorescence spectroscopy. Their energy has been determined with an uncertainty of 0.010 cm−1using a wave number calibrated Fourier-transform spectrum.
