WAVELENGTHS AND OSCILLATOR STRENGTHS OF TRANSITIONS IN Kr XXXIII AND Kr XXXIV

Measurement of the B+and Al+intercombination and Sc12+forbidden transition rates at a heavy-ion storage ring

“…For a discussion of these finer points from the view of theory, see [55]. The present results for B + , together with the precise measurement for C 2+ [7] (using the same technique as in the present work), the very recently improved beam-foil result for Fe 22+ [56] and the earlier beam-foil data for Kr 32+ [57] and Xe 50+ [58], now form a set of reliable data which can serve as orientation markers for theory [59] or for semiempirical interpolation methods [60]. The data at the same time belong to one of the longest isoelectronic sequences of lifetime measurements.…”

Time resolved EUV spectroscopy on foil-excited 5.9 MeV/u Xe and 13.2 MeV/u Au ions

“…The resonance transitions in such ions have therefore been studied up to very high ionization stages, using a variety of techniques [1][2][3][4][5][6][7]. This effect has been studied for the case of a simpler approximate one-electron system 15 years ago, using highly charged 36Kr ions [16]. Nevertheless, calculations of this "one-electron spectrum" need to take into account many-body properties and higher-order effects of atomic structure, relativity as well as quantum electrodynamics (QED), in order to reproduce the experimental data (see [8][9][10][11][12][13][14][15] and references to earlier work therein), At high nuclear charge Z the resonance lines 3s 2S1/2 -3p 2P°/2,3/~ in Na-iike ion spectra separate because of the relativistic effect of spin-orbit coupling.…”

Quest for experimental M1 and E1-intercombination transition probabilities in few-electron Xe ions

“…For C 2+, a measurement using a radiofrequency ion trap [43], and for Fe a2+ [44] and Kr 32+ [45,46], measurements on fast ion beams have been reported. For C 2+, a measurement using a radiofrequency ion trap [43], and for Fe a2+ [44] and Kr 32+ [45,46], measurements on fast ion beams have been reported.…”
