Abstract

From collision-induced fluorescence spectroscopy measurements, we have determined the transition probability A of the 5971-Å transition in neutral uranium. Our value, A<sub>5971</sub> = (5.9 ± 1.8) × 10<sup>5</sup> sec<sup>-1</sup>, is, within experimental error, in good agreement with the previous determination of Corliss, <i>A</i><sub>5971</sub> = (7.3 ± 3.0) × 10<sup>5</sup> sec<sup>-1</sup> [J. Res. Nat. Bur. Stand. Sect. A <b>80</b>, 1 (1976)].
