Abstract : It is demonstrated that the linear response scheme within the framework of density functional method can provide reliable atomic data for various atoms and ions of experimental interest. This model is particularly useful in those situations where conventional independent particle models fail to generate accurate data. The atomic structure code for multielectron ions of arbitrary Z is of central importance in these calculations. Proper relativistic treatment is included in our work for high Z ions. The mechanism of time-dependent polarization of the atom is seen to be important in describing the experimental observations. For most experimental situations, the present method is adequate and very useful. If the applied radiation field strength is very high, suitable generalization of the present model or developement of new techniques are necessary to treat those conditions.
