Observation of an intensity anomaly in the 3s²3p ²P_{1/2, 3/2}-3s3p²²S_1/2 and ²P_1/2 resonance transitions in the Al I isoelectronic sequence

Summary, in English

The intensity ratio of the two fine structure components in the 3s²3p ²P_J–3s3p ²S_1/2 and ²P_1/2 resonance transitions has been measured in Al-like S IV, Cl V, Ar VI and Ti X, using the beam-foil technique. Unexpectedly large deviations from the LS ratios are found, particularly in the ²P–²S case. Although these deviations can be understood qualitatively from theoretical calculations (also reported), large quantitative discrepancies are observed in the beginning of the sequence.
