Abstract
The radiative lifetimes of the levels in the 3d 94s(1 D)4p configuration of Cu I are measured. The levels are excited from the metastable 3d 94s 2 2 D 3/2,5/2 levels. The metastable Cu atoms are generated in a pulsed hollow cathode discharge. The levels investigated are populated with a 35-ps laser pulse at wavelengths around 220 nm. The laser induced fluorescence signal is detected. The lifetime of the 3d 94s(3 D)4p 4 D 1/2 level is also determined by direct excitation from the ground state. A comparison with calculated literature values is given.
