摘      要：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 2s2p 1Po1, 2p2 1S0, 2p2 3P1, 2p2 3P2, 2p2 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 3Po1, 2s22p 2Po3/2–2s2p2 2P1/2, 2s2p2 4P3/2–2p3 4So3/2, 2s22p 2Po1/2–2s2p2 2D3/2, 2s2 1S0–2s2p 1Po1, 2s2p1Po1–2p2 1S0, 2s2p3Po0–2p2 3P1, 2s2p 3Po2–2p2 3P2 and 2s2p 3Po1–2p2 3P0. Most of the experimental results are in agreement with theoretical studies, but differ slightly from the previous experimental data.
