Intercombination transitions in beryllium-like and boron-like iron
by R Hutton, I Martinson, B Nyström, K Ando, Y Awaya, P Bengtsson, T Kambara, Y Kanai, T M Kojima, Y Nakai, et al.
Beam-foil spectroscopy techniques have been used to study intercombination transitions in Be-like Fe²²⁺ and B-like Fe²¹⁺. The method of time delayed spectroscopy was used to identify the Be-like 2s² ¹S₀-2s2p ³P₁ and B-like 2s²2p ²P_3/2-2s2p² ⁴P_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 ³P₁ level and 14.8 ± 1.0 ns for the B-like 2s2p² ⁴P_5/2 level.

Experimental lifetimes for Mg-like chlorine
by L. Engström, P. Bengtsson, C. Jupén, A. E. Livingston, I. Martinson
The results of beam-foil measurements of lifetimes for low-lying singlet levels in Mg-like chlorine, Cl v i, are presented. The decay curves were analyzed by means of the arbitrarily normalized decay curve method, combined with the recently developed c a n y l code, which facilitates studies of decay chains. Cascade corrected data are presented for the levels 3s3p ${}^{1}$ P, 3 $p^{2}$ ${}^{1}$ S, 3 $p^{2}$ ${}^{1}$ D, and 3s3d ${}^{1}$ D, whereas less rigorous lifetime values, based on curve fits, were obtained for the 3p3d ${}^{1}$ D, 3p3d ${}^{1}$ F, and 3s4f ${}^{1}$ F levels. The data are in excellent agreement with recent theoretical values, and previous discrepancies between experiment and theory for short-lived states have been removed.

Relative excitation functions for singly-excited and core-excited levels of S v–S ix populated by the beam-foil interaction
by D. Mönke, P. Bengtsson, L. Engström, R. Hutton, C. Jupén, M. Kirm, M. Westerlind
We have investigated the relative excitation functions for low-lying singly excited and low-lying core-excited levels in S v ( $S^{4 +}$ ) to S i x ( $S^{8 +}$ ) after beam-foil excitation using ions in the energy range 2–10 MeV. The spectral line intensities have been normalized to the same number of particles at each ion energy and corrections for the level lifetimes have been made. The overall accuracy of the measured relative excitation function at each energy and charge state is estimated to be better than 2%. A comparison of the relative excitation functions for singly excited and core-excited lines shows a difference in S v i i, but not in S v i.

Experimental investigation of J-dependent lifetimes in the quartet terms of the 2s2p3p and 2s2p3d configurations in O IV
by M Westerlindt, P Bengtsson, M Kirm, L Engstrom
The paper reports lifetime measurements of quartet levels in the 2s2p3p and 2s2p3d configurations in B-like oxygen, O IV, by means of the beam-foil technique. Reliable decay-times are obtained by explicitly including the dominant cascade repopulation in the decay curve analyses through the non-linear ANDC method. Different fine-structure levels in the 3p ⁴D and 3d ⁴F terms are found to have significantly different lifetimes due to the occurrence of spin-forbidden and Delta L=2 combinations, respectively. A comparison of the experimental 3p ⁴D and 3d ⁴F lifetimes in N III, O IV and F V with recently published theoretical results shows an overall agreement but also some surprising discrepancies.
