Abstract Oscillator strength f-values for L-shell transitions in highly ionized sulfur are studied by the beam--foil technique at the HI-13 tandem accelerator in China Institute of Atomic Energy. The lifetimes of the upper levels 2s2p1P01, 2p2 1S0, 2p2 3P1, 2p2 3 P2, 2 p2 3P0 of Be-like sulfur are measured to be 129±4, 81±5, 165±7, 159±8, 176±11ps. By using the measured lifetimes, the f-values are calculated to be 0.074, 0.082, 0.060, 0.066, 0.229, 0.056, 0.083, 0.089, 0.028 for the transitions 2s22p2 3P1-2s2p3 3P01, 2s22p 2P03/2-2s2p2 2P1/2, 2s2p2 4P3/2-2p3 4S03/2, 2s22p 2P01/2-2s2p2 2D3/2, 2s2 1S0-2s2p 1P01, 2s2p1P01-2p2 1S0, 2s2p3P00-2p2 3P1, 2s2p 3P022p2 3P2 and 2s2p 3P01-2p2 3P0. Most of the experimental results are in agreement with theoretical studies, but differ slightly from the previous experimental data.
