Abstract

In the framework of a unified approach, based on the representation of Stark broadening of spectral lines as an effect of both static and dynamic polarization of the level, a universal description of ionic forbidden line spectral intensity is obtained which includes static and impact limits. The broadening is treated in terms of non-resonant Raman scattering of the Fermi equivalent photons which simulate the electric fields of perturbing particles. The interrelation between this Raman scattering and correlation theory is traced. It is shown that the intensity of forbidden lines due to electronic impacts in hot plasmas with multicharged ions may compete with the intensity due to ionic static action.
