The redistribution function for resonance radiation in the L{sub {alpha}} spectral line of hydrogenic ions in a dense hot plasma is calculated. The calculation is based on a self-consistent solution of the equations for the populations of the excited ionic sublevels and for the polarizations of the transitions considered. Nonlinear interference effects due to mixing of atomic states in both static and dynamic ionic fields are thereby taken into account. Molecular dynamics methods are used to account for the evolution of the multiparticle ionic field resulting from thermal motion of the ions. We calculate the L{sub {alpha}} line of the hydrogen-like argon ion in a plasma with electron temperature 1 keV and electron density N{sub e}=10{sup 22} divide 10{sup 24} cm{sup -3}. The rescattering function is compared with the approximation provided by complete frequency redistribution. The results demonstrate the limited usefulness of the latter approximation for a plasma consisting of multiply-charged ions.
