A uniform quantum energy approach for studying spectra of the multicharged ions in a plasmas and the electron‐ion collision cross sections is presented. The approach is based on formally exact QED theory by using the relativistic Dirac Hamiltonian for electron–nuclear and electron–electron potentials, the gauge invariant scheme of generation for the optimal one‐quasiparticle representation and the Debye shielding model. The measured and calculated electron‐collisional excitation cross sections for Ne‐like barium ion for different values of the incident electron energy are presented and analyzed. © 2010 Wiley Periodicals, Inc.
