Scientific paper

A consistent theory is developed for describing the effect of the appearance of dipole-forbidden spectral lines (FSL) in a plasma. The theory accounts only for the contributions of quasistatic ions to the FSL intensity, the boundary between these ions and the remaining ions being determined from a multiparticle description of the plasma microfield. The analysis is extended to the more complicated four-level schemes of the energy spectrum of emitters. The results obtained eliminate many of the discrepancies between theoretical and experimental values of the ratio of the intensities of the FSL and allowed spectral lines (ASL). The effects of quadrupole interaction, caused by inhomogeneity of the disturbing microfield on the intensities of FSL, and corresponding ASL intensities, are analyzed. It is shown that, in dense high-temperature plasmas, quadrupole interactions may dominate. Their contributions to FSL and ASL intensities are calculated analytically for the multiparticle description of the plasma microfield.
