Lifetimes of low-lying doublet states in S IV

Summary, in English

Intensity decays of the 3s3p2 S2,2P,2D, 3p3 P2,2D, 3s3p(3P)3d D2, 3s3p(1P)3d F2, 3s23d D2, 4s S2, 4p P2, 5p P2, 4d2D, and 4f 2F states in S S IV have been recorded using the beam-foil technique. The arbitrarily normalized decay curves method for cascade corrections has been applied to obtain accurate lifetimes for 11 of the 18 levels studied. Theoretical lifetimes for these levels, obtained in a superposition-of-configurations calculation, are also reported, and several interesting examples of both long- and short-range interactions are discussed.
