  The new statistical approach for calculation of radiation processes with
heavy multielectron ions in plasma is developed. The method consists in
consideration of atomic structure as a condensed medium, characterized by the
spectrum of elementary excitations with plasma frequency, determined by local
atomic electron density. For instance, the radiation losses in this model are
due to excitation of plasma type oscillations in atom under its collisions with
plasma electrons and have a universal statistical representation for all sorts
of multielectron ions. The calculations of radiation losses on tungsten ions
are performed in the wide range of plasma temperature variation, typical for
physics of high temperature plasma with magnetic confinement. It is shown that
the universal statistical approach results are within the scattering of current
numerical codes data. The proposed statistical method for description of
complex atoms collective excitations for calculations of plasma radiation
losses is of general physical interest and allows to obtain the necessary data
more faster with the lesser computational resources.
