A beam-foil study of lifetimes in Ga I, Ga III, Tl I, and Tl III

Abstract Lifetimes have been deduced from beam-foil decay curves for 6 Ga I terms, 7Ga III terms, 7 Tl I terms, and 2 Tl III terms. The results are compared with numerical Coulomb approximation calculations as well as with previous experimental and theoretical data and discussed. There is generally good agreement between experimental and the numerical Coulomb approximation.
