In the EUV spectrum of foil-excited 24 MeV Ni ions the decays of the 3 s 3 p3 and 3 s2 3 p 3 d levels to the 3 s2 3 p2 levels of the ground configuration have been observed. For most of the levels decay curves have been obtained. The lifetime results compare well with predictions from semi-empirically scaled HXR calculations. Some problems with cascade repopulations will be discussed.

An experimental and theoretical study has been made of the 3s-3p and 3p-d transitions in Ni XIX. The method of beam-foil spectroscopy, using 30-64 MeV Ni ions from a tandem accelerator, has been combined with theoretical calculations using the multiconfiguration Dirac-Fock (MCDF) program.

By means of the beam-foil method, 74 new lines have been identified as combinations between the core-excited 2p5 3s3p, 3s3d and 3p2 configurations in Na-like sulphur, chlorine, argon and titanium. Relative energies have been determined for most of the quartet levels in S, Cl and Ar with an internal uncertainty of less than 25 cm−1. We also report the first observation in the isoelectronic sequence

Using the beam-foil excitation technique and the ANDC method for cascade corrections, we have determined lifetimes of the 2s2p22S, 2s2ns2S (n = 3, 4, 5), 2s2p22P, 2s2p2P° (n = 3, 4), and 2p32P° terms in CII and the 2s2p1P0 level in C III. The new experimental lifetimes are in very good agreement with the results of recent theoretical calculations.

Using the method of beam-foil spectroscopy we have measured the decay times of several n = 3 terms in Mg-like Ni XVII. By applying an effective method for correction of cascades (ANDC) we obtained reliable lifetimes for the terms 3s3p1P, 3s3p3P, 3p21D and 3p2 3P. The experimental data are in good agreement with recent theoretically predicted values.

Intensity decays of the 3s3p2 S2,2P,2D, 3p3 P2,2D, 3s3p(3P)3d D2, 3s3p(1P)3d F2, 3s23d D2, 4s S2, 4p P2, 5p P2, 4d2D, and 4f 2F states in S S IV have been recorded using the beam-foil technique. The arbitrarily normalized decay curves method for cascade corrections has been applied to obtain accurate lifetimes for 11 of the 18 levels studied. Theoretical lifetimes for these levels, obtained in a s

Lifetime measurements, based on the method of beam-foil spectroscopy, together with careful corrections for cascade effects, have in recent years yielded the line strength of the 2s2 1S-2s2p 1P°transition in Be-like ions with uncertainties ranging from 3.4% to 8.1% in Bei-O. By applying a method of isoelectronic smoothing of line strengths, similar to those earlier used for excitation energies and

The intercombination transition 3s21S0 -3s3p3P1 0 in Ni16+ and Cu17+ has been studied by beam-foil spectroscopic methods. Decay curve analysis yields lifetime values of (12.0±1.0)ns and (8.8±0.6)ns for Ni and Cu in agreement with various predictions.

The changing structure of the Swedish university system has shaped its corps of university teachers. The analytical device used to demonstrate this connection is the changing social functions of Swedish universities which serve as the lens through which we understand this change. We argue for five successive and historically added layers of functions: the training of church officials, state functi

This thesis aims to provide an understanding of the existing cultural plurality and diversity in Burgazadası, within a post-Ottoman and homogenising context in Turkey. Most of the scholars working on conflict resolution and peace projects in the Balkans and the Middle East have attempted to analyse cultural plurality with the concept of “coexistence”. “Coexistence” as a concept presupposes the pre
