Radiative lifetimes of 8 different multiplets in the visible range in neutral sulphur have been directly measured using the High Frequency Deflection technique. These lifetimes have not been experimentally studied earlier. The results are compared to Coulomb approximation calculations and semiempirical estimates of the associated oscillator strengths.
Radiative lifetimes of eleven C1 I transitions in the visible range of the 4s-np and 4p-nd arrays have been directly measured for the first time. The results are compared with emission experiments and compilations of transition probabilities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
