Abstract
A new approach to the solution of high dimension spectral problems, which is based on the use of the moment method (kernel polynomial method), is applied to study many-particle effects in a series of alkali fluorides. The electronic structure, absorption spectra, the features of the electronic charge distribution caused by the formation of bound electron-hole states and changes in these distributions in a series of fluorides due to distinctions in their electronic structure are analyzed.
