Abstract Natural radiative lifetimes have been measured of the 3d 10 ns 2 S 1/2 (n=6−10) and of the 3d 10 nd 2 D 3/2, 5/2 (n=5−9) sequences by using two step excitation of copper atoms in an atomic beam. The states investigated were populated by the light from two pulsed dye lasers pumped by the same Nd:YAG laser. The lifetimes of the2 D sequence increase regularly with increasing principal quantum number. This is not the case for the2 S series, because of configuration interaction in the2 P series. In addition the lifetime of the 3d 105p 2 P 3/2 state has been measured together with its branching ratio.
