BEAM-FOIL MEASUREMENTS OF ATOMIC LIFETIMES

This paper discusses recent progress made in the measurement and analy sis of atomic lifetimes using the beam-foil technique. In particular t he problems associated with measurements for short-lived (ps) levels a nd levels subject to significant cascade repopulation will be addresse d. A review will also be presented of recent experimental and theoreti cal studies of the decay-dynamics for quartet levels in the 2s2p3p and 3d configurations along the B I isoelectronic sequence.
