Hyperfine-induced effects on the linear polarization ofKα1emission from heliumlike ions

et al. 2013

The linear polarization of the characteristic photon emission from few-electron ions is studied for its sensitivity with regard to the nuclear spin and magnetic moment of the ions. Special attention is paid, in particular, to the Kα1 (1s2p 3/2 1,3 P1,2 → 1s 2 1 S0) decay of selected helium-like ions following the radiative electron capture into initially hydrogen-like species. Based on the density matrix theory, a unified description is developed that includes both, the many-electron and hyperfine interactions as well as the multipole-mixing effects arising from the expansion of the radiation field. It is shown that the polarization of the Kα1 line can be significantly affected by the mutipole mixing between the leading M 2 and hyperfine-induced E1 components of 1s2p 3 P2, Fi → 1s 2 1 S0, F f transitions. This E1-M 2 mixing strongly depends on the nuclear properties of the considered isotopes and can be addressed experimentally at existing heavy-ion storage rings.

“…This effect has been theoretically studied in a number of cases e.g. [3][4][5], but there are only a few experimental values to compare with. The hyperfine structures of levels in the 5s 2 1 S 0 -5s5p 3 P o 1 and 5s5p 3 P o 1,2 -5s6s 3 S 1 transitions were accurately determined by Larkins and Hannaford [6] using a high-resolution scanning echelle monochromator.…”

We report extensive relativistic multiconfiguration Dirac-Hartree-Fock calculations of oscillator strengths and hyperfine structures for a large number of electric dipole transitions in In II. Results for the 5s 2 1 S 0 -5s5p 3 P o 0 hyperfine induced transition are also presented. Core polarization is accounted for by means of explicit CI. To describe spin-polarization effects configuration state functions obtained by single excitations from all core-shells are included in the expansions. The computed oscillator strength for the 5s 2 1 S 0 -5s5p 3 P o 1 intercombination transition is in good agreement with laser spectroscopy measurements of In + ions in a radio-frequency trap. The calculated magnetic dipole hyperfine interaction constants agree very well with experimental constants derived from Fourier transform spectra. The problem with offdiagonal interactions affecting the hyperfine structures in closely spaced finestructure levels is discussed.

Abstract. In this work we use the multiconfiguration Dirac-Fock method to calculate the transition probabilities for all possible decay channels, radiative and radiationless, of a K shell vacancy in Zn, Cd and Hg atoms. The obtained transition probabilities are then used to calculate the corresponding fluorescence yields which are compared to existing theoretical, semi-empirical and experimental results.
