Measurement of the lifetimes of the z²F_5/2, z²D_3/2, z⁴G_5/2, and y²D_3/2 states of lanthanum

Abstract

The lifetimes of the 5d 6s (¹D)6p z²F_5/2, 5d 6s (¹D)6p z²D_3/2, 5d²(³F)6p z⁴G_5/2, and 5d 6s (³D)6p y²D_3/2 states of La i have been measured using time-resolved spectroscopy following excitation by a pulsed dye laser. The measured values for the lifetimes are 120 ± 6, 165 ± 8, 51 ± 4, and 18 ± 3 ns, respectively.
