An atomic impurity in a high density plasma

We present a self-consistent theory based on the local density functional approach to study the electron structure of an atom imbedded in a high density plasma. We consider a neon atom as an impurity relevant to high compression laser fusion experiments for our analysis and indicate the usefulness of this approach to study level shifts where linear theories like Debye-Hueckel or Thomas-Fermi model will fail.
