Abstract
Natural radiative lifetimes have been measured for the 3s 2 ns 2 S 1/2 (n≦10) and 3s 2 nd 2 D 5/2,3/2 (n≦11) sequences of aluminum using pulsed laser excitation of an atomic beam. The investigated states were populated from the ground configuration using UV pulses of wavelength down to 210 nm produced by a Nd: YAG- or an excimer-pumped dye-laser system. TheS-state lifetimes increase regularily with increasing principal quantum number but this is not the case for theD sequence.
