| Abstract: | We have measured the radiative lifetime of the (5d6p)3D3 state of barium by Hanle effect. This state was populated by cw dye laser excitation of an atomic beam of Ba in the metastable (5d6s)3D3 state. The metastable state was populated by a dc discharge. With dye laser excitation, the shape of the Hanle effect curve is strongly modified due to optical pumping of the metastable state. A brief discussion of the expected and observed signal shapes is given. The radiative lifetime of the (5d6p)3D3 state is measured to be τ = 10.2 ± 1.5 ns. |
