摘要：
Beam-foil spectroscopy techniques have been used to study intercombination transitions in Be-like Fe22+ and B-like FeZ1+. The method of time delayed spectroscopy was used to identify the Be-like 2s(2) S-1(0)-2s2p P-3(1), and B-like 2s(2)2p P-2(3/2)-2s2p(2) P-4(5/2) transitions. Intensity decay curves for these transitions were recorded and level lifetimes were obtained. The latter were found to be 17.5 +/- 1.5 ns for the Be-like 2s2p P-3(1) level and 14.8 +/- 1.0 ns for the B-like 2s2p(2) P-4(5/2) level.
