Abstract
The furnace absorption method has been applied to the spectrum of neutral atomic uranium. In the wavelength interval, 355.2 ≥ λ (nm) ≥ 359.4, the absolute oscillator strengths for 57 transitions in neutral uranium have been determined. For the strongest transition at 358.487 74 nm, the result was ƒl: (358.4) = 0.041 ± 0.003. This latter result is in excellent agreement with the absolute oscillator strength derived from three separate lifetime measurements and the calculated branching ratio for the 591.538 74 nm transition.Keywords
