ABSTRACT:We present the uniform energy approach, formally based on the quantum electrodynamics, using the gauge invariant scheme of generation of the optimal one-electron representation, for the calculation of electron-collision strengths and cross sections. The aim is to study, in a uniform manner, elementary processes responsible for emission-line formation in plasmas. The electron-collision excitation cross sections and strengths for some Ne-like ions (Fe, Ba) are calculated. To test the results of calculations, we compare them with the calculations of other investigators and with the available experimental data.
