摘要：
From spectra of a very weak barium hollow-cathode discharge obtained with a Fourier-transform spectrometer, the branching ratio between the visible resonance line at 553.5 nm and the infrared line at 1500 nm of the barium atom was determined to be 485±40. Given the known lifetime and branching fractions between the infrared lines originating in the resonance level, it is now possible to present definitive branching fractions and transition probabilities for all transitions out of the 6s6p 1P1°barium resonance level. © 1990 The American Physical Society.
