摘要：

Problems associated with the measurements of lifetimes in heavy or complex atoms and ions are discussed. Besides the now classical beam-foil method, two new techniques are introduced, which both utilize fast-beam/cw dye-laser modulation spectroscopy. Lifetimes are reported for excited states in Ne I, Zr I, Au I, Tl III, U I, and U II. The advantages of the selective laser-based techniques as compared to the beam-foil method are discussed.
