The natural width of the strong Fe I spectral line λ=3719,9 Å was determined in a double resonance experiment with an atomic beam as resonance cell and a hollow cathode as light source by the observation of rf-induced magnetic dipole transitions between the Zeeman sublevels of the excited state in a weak static magnetic field H 0. The optical line was isolated from disturbing neighbours in the same multiplet either roughly by an interference filter or strictly by a monochromator. From the width Δν=5,35(14) MHz of the double resonance signal (monochromator value, including a small correction of 1.5% for the hyperfine structure of the 2.2% natural abundance of iron-57) the lifetime τ of the ( z 5 F {5/0})-level is found to be τ=5,95 (16)×10-8 sec. The f-value of the transition to the ground state ( a 5 D 4) is calculated, by using the known relative f-values for the weak alternative transition possibilities to the ( a 4 F 5) and ( a 5 F 4) levels ( λ=5012 and 5127 Å), to be f λ3720=4,21 (11)×10-2.
