Generalized energy approach in an electron-collisional spectroscopy of multicharged ions in plasma in the Debye approximation

Abstract

The generalized relativistic energy approach is used for the studying the spectra of plasma of the multicharged ions and calculation of electron-ion collision strengths, cross-sections in Ne-like ions. The approach is based on the Debye shielding model relativistic Dirac Hamiltonian for electron-nuclear and electron-electron potentials and energy approach. The relativistic many-body perturbation theory with using gauge-invariant scheme of generation of the optimal one-electron representation is used. The measured and calculated electron-collisional excitation cross-sections for Ne-like barium for value of incident electron energy 8.20keV and the effective collision strengths of the Ne-like krypton excitation states for temperature T=5×106K and electron density ne=1014cm−3 are presented and analysed.
